Laser Deep Welding: Principles, Advantages, and More

Laser Welding: An In-Depth Look at Deep Welding Techniques

Laser welding is an essential and versatile technique widely used across industries such as manufacturing, automotive, aerospace, and electronics. This method has two primary types: continuous and pulsed, further classified into heat-conductive welding and laser deep melting welding. This article will delve into laser deep welding, discussing its principles, key factors, and advantages and disadvantages.

Principles of Laser Deep Welding

Laser deep welding employs a continuous laser beam to join materials, sharing similarities with electron beam welding in its metallurgical process. A critical aspect of this technique is the formation of a "keyhole" structure, essential for energy conversion. Here are the main stages of the laser deep welding process:

Energy Absorption: The material’s ability to absorb laser energy varies based on its properties, including absorption rate, reflectivity, and thermal conductivity. Non-metallic materials like ceramics and plastics absorb laser energy well at room temperature, while metals exhibit low absorption rates until they melt or vaporize.

High Energy Concentration: When exposed to a high-power laser, a small, vapor-filled hole form, absorbing nearly all incident energy. The temperature within this cavity reaches around 2500°C.

Molten Metal Formation: Heat transfer from the high-temperature cavity’s outer walls causes the surrounding metal to melt. As the wall material evaporates, vapor fills the hole, creating a molten metal layer around it.

Continuous Flow: The molten metal flows outward, and surface tension maintains a dynamic balance with the cavity's vapor pressure. As the laser moves, this molten "keyhole" structure follows, enabling high-speed welding at rates of several meters per minute.

Key Parameters Affecting Laser Deep Welding

Several factors influence the effectiveness of laser deep welding, including:

Laser Power: Higher laser power density enhances melting depth and welding speed.

Beam Focal Spot Size: A smaller focal spot increases power density, affecting weld penetration.

Material Absorption Rate: The absorption rate and surface condition impact laser energy absorption.

Welding Speed: Adjusting the speed can control melt depth. Optimal speed varies by material, power, and thickness.

Protective Gas: Inert gases like helium, argon, and nitrogen protect the molten pool, prevent oxidation, and disperse plasma.

Lens Focal Length: The lens focal length affects power density and spot size, with shorter focal lengths producing smaller spots.

Focus Position: The focal point’s position relative to the workpiece surface impacts weld width and depth.

Laser Beam Position: Precise control of the laser beam’s position is crucial, particularly in butt joint welding.

Gradual Power Control: Gradual power adjustments at the start and end of welding help avoid defects like pits and excessive melting.

Advantages and Disadvantages of Laser Deep Welding

Laser deep welding provides multiple benefits:

High Depth-to-Width Ratio: Produces narrow, deep welds.

Minimal Heat Input: Reduces thermal distortion and heat-affected zones.

High Weld Density: Results in strong, high-quality welds with low impurities.

Precise Control: Allows accurate beam positioning and is suitable for automation.

Non-Contact Process: Welding occurs without physical contact, protecting the workpiece.

Cost-Efficiency: High welding speeds and low operating costs improve overall efficiency.

However, laser deep welding also has some limitations:

Limited Welding Depth: The technique has constraints on maximum weld depth.

High Assembly Requirements: Accurate alignment and assembly of workpieces are necessary.

High Initial Investment: Laser welding systems require a significant initial cost.

Conclusion

Laser deep welding is a powerful and adaptable welding technique valued for its ability to produce deep, high-quality welds with minimal heat input and precise control. Although initial costs and depth limitations exist, its benefits often outweigh these drawbacks, making laser deep welding a valuable tool in modern manufacturing and fabrication.

Laser welding as a high-energy beam precision welding technology, with its low thermal input, small welding deformation, welding speed, high degree of automation, a series of advantages, more and more widely used in the industrial field.

However, in Dotslaser welding, if the arc section and the arc collection section do not carry out special process treatment, then due to the machine tool or robot and other moving body of the acceleration process, at the beginning of the weld is prone to appear "match head" appearance, the end of the weld is prone to arc pit depression, the overall uniformity of the weld appearance has a greater impact, and the arc at the end of the arc will reduce the strength of the weld, easy to produce arc cracks. And the greater the laser power density, the more obvious this phenomenon.

Therefore, in the actual production process, the weld arcing and arcing process needs to be special treatment. If the weld position and conditions allow, can be avoided by adding an introduction arc plate, but in the actual mass production, this scheme is not applicable, and part of the weld trajectory is closed graphics, weld start and end segments are in the weld, so it is necessary to optimize the weld process parameters to adjust the shape of the weld arc closing segment.

The weld shape can be adjusted by the laser power control and PWM control of the starting arc segment, and during the arcing phase, the power can gradually change from low to high as the moving mechanism accelerates from stationary to normal welding speed, and the power can be changed gradually from low to high, low power in the low-speed stage and high power in the high-speed stage, which can be avoided. At the arc "match head" shape, in the arcing stage, the laser power is gradually reduced, can reduce the energy density of the welding line, the weld melt width gradually narrows, the welding process deep melting hole gradually becomes shallow, thus improving the arc pit shape at the weld arc.

Therefore, by controlling the laser power slowly rising and falling, the weld can be smoothed too smoothly at the start and end of the arc, significantly reducing the height of the weld starting arc point and the size of the arc pit at the end of the arc and depression. On this basis, in order to further control the heat input volume of the starting and ending segments, the dubing ratio or modulation frequency can be optimized again with the change of welding speed.

DOTSLASER uses continuous optical lasers for continuous welding and modulation mode welding, and laser power can be adjusted in real time. With Jept's continuous laser monitoring software, not only can the laser's working status be monitored in real time, but also the line energy density can be precisely controlled, thus avoiding the "matchhead" shape at the arc.

Build A 12V 280Ah LiFePO4 For A Golf Cart! Full Process Of Battery Cell Assembly！

LiFePO4 batteries have lots of advantages and are becoming quite in demand in the market of trolling motors. When referring to the LiFePO4 batteries, you may compare them with the GEL batteries. For a long time, GEL batteries have played a role in our lives. Nowadays, we prefer LiFePO4 batteries.

As opposed to boats that use GEL batteries, electrical ships equipped with the 12.8Volt 280Ah lithium batteries are more economical, less polluting, and clearly better for the environment. The LiFePO4 battery has a longer life span and deep cycle times(even more than 5,000 times).

Are you a Lithium battery amateur and interested in li-ion battery pack assembly? Now we’d like to share the whole assembly process for beginners, which takes the 12.8V 280Ah LiFePO4 battery as an example.

*Note: It is recommended that you learn some basic knowledge about LiFePO4 batteries before assembling the battery pack. Keep safe when you are assembling the battery pack.

Material Used

3.2V 280Ah LiFePO4 battery cells (4 pieces)

There are currently three common shapes of LiFePO4 batteries: cylindrical, prismatic, and pouch. Different shapes of batteries will have a certain impact on performance. At present, the most suitable battery DIY enthusiasts are the prismatic LiFePO4 batteries, which are very suitable for both performance and operational difficulty. 

We recommend you purchase the Grade A battery with a high quality and reliable warranty.

BMS (Battery Manage System, 1 piece)

Connectors (About 4pieces)

Others: EVA cotton, screws, ribbon cable, plastic pipes, etc.

Tool Used:

Spot Welder

Spot Welding Pen

Soldering Iron

Wire Cutter

Wire Stripper

Multimeter

Assembly Methods: 4 Series And 1 Parallel

Series(S): The way of connecting the positive and negative electrodes of two different cells is called a series connection. As a result, the voltage of the battery pack will increase while the capacity remains the same.

Parallel(P): where the positive and positive electrodes of two different cells are connected in parallel. The result is that the capacity of the battery pack increases while the voltage remains the same.

Assembly Process

1. Install Signal Acquisition Wires In Sequence

The connecting piece has been connected to the battery cell by laser welding. Before installing the signal acquisition, we checked the consistency of the battery and fixed them with fiber tape.

2. Cut The Signal Lines To An Appropriate Length

Tidy up the signal lines and tape them with fiber tape, then cut the signal lines to an appropriate length.

3. Soldering Signal Lines With Lead-Free Solder

Generally, leaded solder is composed of tin and lead. The advantages of using leaded solder include: being easier to bring to working temperature, being shock resistant, and having fewer internal flaws in the structure after being cooled. However, lead material is harmful to the body as it’s readily absorbed. We’d better choose lead-free solder to protect our health and environment.

4. Connect The Positive And Negative Power Line With Connecting Pieces

5. Connect The Power Line

6. Connect The B- Of BMS To The Negative Of Battery Pack

A BMS is one of the most important elements in a LiFePO4 battery, like the brain of the battery pack. It calculates the State of Charge (the amount of energy remaining in the battery) by tracking how much energy goes in and out of the battery pack and by monitoring cell voltages, which can prevent the battery pack from overcharging, over-discharging, and balancing all the cells voltage equally.

There are two main sets of wires we need to install, the thick wires and the thin wires. The thick wires are your charging/discharging wires and the thin wires are your balance wires. Not every BMS is the same, but most are similar. Your BMS will likely have 3 thick wires or 3 pads to solder on your own heavy gauge wires. These are the B-, P-, and C- wires (or pads for adding wires). We usually start with the B- wire. We can connect the B- of BMS to the negative pole of the battery pack.

7. Put The Battery Pack Into Shell, And Fill The EVA Cotton

EVA cotton can be shockproof, fireproof, and insulated.

8. Secure BMS With Thermally Conductive Tape

The thermally conductive tape for battery packs keeps the BMS in place and protects them from the shock of extreme temperature changes. 

Besides, these tapes provide electrical insulation, which prevents short circuits and provides a barrier to BMS.

9. Check The Signal Lines In Correct Order

Pay attention, the wrong sequence may cause BMS to burn out!

10. Install Positive And Negative Power Lines To The Cap

11. Plug Signal Acquisition Wires’ Port Into Interface

12. Fill EVA Cotton

EVA cotton can be shockproof, fireproof, and insulated.

Battery Tests

13. Test Voltage Of The Battery Pack

In these steps, we can use a multimeter to check the voltage of the whole battery pack. Attach the multimeter probes to the positive and negative battery terminals. Then we can check the voltage on the screen. The multimeter’s red probe must be connected to the positive terminal, while the black probe must be connected to the negative one.

A fully-charged battery must indicate a slightly higher voltage than the voltage listed on the battery. For instance, a 12 volts battery will indicate about 12.8 volts when it is fully charged.

14. Charging Test

The battery capacity, or the amount of energy a battery can hold, can be measured with a battery analyzer. If you’re doing a capacity test, be sure to charge the battery until the battery reaches 100%. Then discharge the device until the battery is fully depleted. The charge and discharge rates of a battery are governed by C rates. The capacity of a battery is commonly rated at 1C, meaning that a fully charged battery rated at 280Ah should provide 280A for one hour.

15. Discharging Test

The discharging test of the battery is very helpful to the battery cycle life and discharge performance evaluation. We can use a professional device(Such as a Programmable DC Electronic Load) to check whether the battery works well or not during the discharging process, which can protect our battery and devices for further daily using.

When testing, there are three factors we need to pay attention to the port voltage of the battery, the resistance of the wire between the battery and the electronic load, and the temperature of the battery.

Summary

After assembling and testing the batteries step by step successfully, you will get your new 12.8V 280Ah LiFePO4 battery pack! It is suitable for your golf cart or other applications(such as household solar energy storage, Recreational Vehicle, Yacht, etc.)

Thanks for reading the full tutorial on assembling the 12.8V 280Ah LiFePO4 battery! It is not hard for us to build a LiFePO4 battery. Which voltage and capacity of the LiFePO4 battery do you need?

Fanart for @dana-chan-the-control-brain ‘s fanfic tech support: chapter 4 weasel words

 The Computer was broken from his thoughts at the sound of high pitched shrieking. His cameras and processors devoted his attention to the distressed little irken in the experiment room. Who was being attacked by the very same weasels he was experimenting with. Apparently, Weasels did not take kindly to having sleep hypnosis parasites planted in their brains.

Zim ran and shrieked and flailed his arms as the little furry creatures crawled all over him, slathering him with bites, claw marks and laser eyes. A quick scan confirmed that these weasels did not have rabies, they were just angry. VERY angry. And aside from Zim’s panicking and mild bleeding from the bites he appeared unharmed. He was just freaking himself out, making the weasels angrier. He was going to seriously hurt himself if this kept up. Even if it was, admittedly, hilarious to watch.

The Computer wordlessly opened up the weasel containment unit without a verbal command.

“Master, contain the weasels in here.”

Zim then slammed the glass door to the containment unit shut. Panting heavily.

Zim peeled one of the weasels off his face, and threw it in the containment unit. He did the same for the one biting underneath his leggings and two others that were chomping down on his antenna and leg respectively.

“Wheeeeeeeeew… ha… that was a close onnnnAUGHHHH!!!”

Zim reached a new octave as he realized he didn’t notice the weasel clinging to his PAK, that had begun clawing the shell, causing a port to open up and began nibbling on wires to it’s heart’s content.

“AHH! NO NONONONONONONONONO!!! GET OUT OF THEREEEE!”

Zim tried to reach behind his back but instead he squeaked and convulsed as his eyes rolled back and his antenna twitched. He spun around in a circle and fell to the floor, before leaning back upright with his bodyweight only. Jerking and moving in an unnatural way. As if he didn’t have control of his own limbs. His arms and legs behaved like noodles as if the weasel was hosting the world’s worst grotesque puppet show. Zim’s tongue rolled out his mouth as his PAK began flashing red as a warning.

Now this was something the Computer WOULD intervene with. A robotic arm descended from the ceiling and snatched the weasel off Zim’s back, and threw it in the containment unit unceremoniously, crashing it into all it’s other bite-happy brethren before sealing them up again.

Zim fell to the ground, moaning and twitching.

Was he alright?

The Computer ran a scan of Zim’s current state. Specifically his PAK. He cross-compared reference to the scan he took on the first day Zim arrived to Earth. He didn’t have time to go over Zim’s PAK data in depth yet. Between GIR’s food experiments and Zim’s animal experiments, he had a feeling he'd be in pretty high demand over the weekends.

“Master,” The Computer began, speaking in an authoritative neutral voice. “Some nerve ending wiring for your arm control nerve is frayed along with your limb systems and several other nerve wirings. I'll plug in and begin an automatic PAK repair as soo-”

“NO!” Zim shrieked, far more panicked then the Computer ever heard him, and that was saying a lot judging by how jumpy he was.

“N-No.” Zim stammered, shakily getting to his feet, swaying where he stood. “There’s no need for an automatic PAK repair… I can do it myself.”

“......I… what? Are you sure? You can barely stand right now.. And your arms are very limp and...shaking....” The Computer couldn’t help but say aloud.

“Ah, Don’t worry, it’s just a little scratch and some loose wires, it’s fine!” Zim extended his PAK legs to walk to the PAK repair work station, as opposed to walking on his little organic legs that were trembling like jelly. Thankfully, that part of his PAK was undamaged as he was able to extend and use his PAKlegs no problem.

“...With all due respect, Master…” the Computer began as Zim leaned his body against the console, trying to figure out how to word what he would say next. “I don’t believe in your current condition that you would be able to repair your PAK manually.”

For a moment, Zim said nothing. He didn’t snap at him immediately like he normally did. Which worried him. He just leaned his head against the console, closing his eyes for a few moments.

“....Master?”

“EH!?” Zim’s antenna shot upwards and he looked confused. As if he wasn’t talking to him a few seconds ago.

That was very worrisome.

“Let me repair your PAK.” The Computer said in the most soft and stern voice he could muster.

Zim’s antenna twitched, as he realized what the Computer was asking.

“Eh.. Ah, no, don’t worry about it! I’m FINE!”

Before the Computer could argue his reasoning some more, Zim turned around so he could face the workbench and detached his PAK onto the work station. The PAK extended a few extra port wires and crawled onto the bench obediently, apparently used to this type of repair from its host. The lifeclock in the Computer’s systems activated, displaying the ten minute time limit in the center screen of every single camera in the home. A normal precaution so Invader Computers were currently aware when the PAK was attached to their Master and if they were at any risk of dying.

Zim arched his back and gave a long stretch that cracked his spine. He took a deep breath as he flexed his arms and claws, and began blinking each eye separately at a time and flexing his antenna individually from each other. The Computer observed him for a few moments. He consulted his database to see if such behavior was common for irkens who performed manual PAK repair. Oddly, there weren’t many instances of manual PAK repair operated by the irken host itself. PAK maintenance drones would repair other irkens typically, but not themselves. Invaders were trained in basic first aid, due to the nature of their job. They had to spend long quantities of time alone, and basic wear and tear maintenance was expected in their line of work.

A few chewed off wires however, that’s a different story.

“...Are you sure you know what you’re doing?” The Computer began hesitantly, suspecting that Zim had no clue what he was tampering with. He can never know with him.

Zim flexed his claws a few more times before he seemed satisfied, and he grabbed the wielding tool from overhead.

“Huh-hmm.” Zim said plainly. “This kinda thing happens all the time.”

“...You…. your wires get chewed out by weasels all the time?” The Computer asked.

“Yes! Well, no. Well.. I just mean… ya know… trainee combat and all that.”

Invader training combat?.... Zim had his wires yanked out of him before? The Computer suspected that was highly unlikely. Due to the nature of an irken’s PAK, and how they held most of an irken’s consciousness and served as a secondary brain to work alongside their primary one, PAKs were strictly off limits from attacking. Especially during training and simulations. In fair duels one of the main rules is to not mess with a fellow irken’s PAK. Everything else is fair game. Punch them in the eye, yank their antenna or grind the heel of their boot into the spooch. Attacking or tampering with an Irken’s PAK is strictly forbidden and would cause low marks and demerits, and in extreme cases, re-encoding.

“...How does that happen?” The Computer couldn’t stop himself from asking.

“Ah, oh ya know how training is..” Zim said distractedly as he began welding and repairing the loose wires. “Stomping or yanking of the PAK to see how long I can last, throwing it back and forth amongst the Elites, hitting it a bit with the brunt of the electro spears a bit too hard…that’s just how it goes. All normal endurance training for only the most elite of the elite.”

…….He was kidding? Right?

"Like this one time during training, my PAK was yanked off and my fellow soilders wanted to see how long I could last, and that skilled Invaders are able to survive past the ten minute mark. Well, my record is about three minutes till. So we waited. They kept it away from me a little bit past my record, one minute was cutting it a little close, but we all had a good laugh about it."

He wasn’t kidding.

“They are just testing to make sure I have the right endurance! They obviously were testing my durability and enguitity! I had to learn a few things about PAK repair if I wanted to complete my Invader training! A few dents and dings like this is nothing.”

.....

The Computer immediately pulled up any information he had based on Zim’s training days as an Elite. He couldn’t find any documented evidence that his fellow elites had bullied him like this, but he did notice the peers he was typically stationed with at the time.

ELITE RED:

SKILLED TACTICIAN AND IMPRESSIVE COMBAT SKILLS

HIGHLY FAVORED BY FORMER ALL MIGHTY TALLEST MIYUKI

CURRENT STATUS: ALL MIGHTY TALLEST RED

ELITE PURPLE

RUTHLESS NO MERCY APPROACH TO COMBAT.

TOP SCORES IN STEALTH

CURRENT STATUS: ALL MIGHTY TALLEST PURPLE

That….

That can’t be right.

That would be impossible.

Logical evidence would suggest that these two were the ones that would purposely mess with Zim’s PAK to give him clear and unfair advantages. However, the Tallest are all powerful and all knowing in their judgements. They wouldn’t have become the Tallest if they were breaking the rules as elites. Even then, while Zim was the runt of his squad, he didn’t deserve such treatment. Either Zim did not know of the protocols or he thought that it was a standard part of training.

But… Zim had to be lying? Right? I mean he’s defective, who knows what crazy thinks?

That’s what the Computer wanted to think. But watching Zim calmly and accurately repair his PAK as if it was normal routine for him suggested otherwise. He’s been at it for about a minute now.

“...Master.” The Computer said lowly and softly, lowering the probability of startling him.

“Hmmm?” Zim responded, laser-focused on his task.

“How are your hands so steady…. You were flailing around with limp arms not to long ago… and your PAK is still damaged.”

Zim blinked up from his work, pausing for a moment before he gave a soft chuckle. It was unlike when Zim laughed loudly to assert his dominance. It was squeaky and soft.

“Silly Computer!” Zim chuckled and he got back to work.

“...Uhhhhh..”

Zim snickered to himself. “You’re a machine, so I don’t expect you to get it.”

What? What was so funny?

“My PAK has been damaged.” Zim then pointed towards his temple. “Not my ORGANIC brain.”

“....I …..”

“Once the PAK is detached, my biological shell draws resources from the organic brain. The nerve endings in those are FINE. It’s the PAK that’s the problem.”

The Computer considered this. While what Zim was saying was true, most irkens didn’t tend to view themselves as a disconnect to their PAK. It was a level of heightened awareness not many had achieved. If an iken’s PAK was damaged, it was common they would still experience pain once it was detached. There were many reports of a PAK being damaged, the PAK thinking that it’s host has broken a leg, and once the PAK was removed, the irken biological shell would still feel as if their leg is broken. Only PAK technicians had this level of understanding on how the PAK brain and organic brain co-exist together.

“You know, for an Irken super Computer, you’re not that smart if you forgot how PAKs work.” Zim snickered.

Oh that little…

“I have not!” The Computer huffed. “Just seeing this level of competence from you is shocking.”

“I know, I know. I am truly amazing!” Zim beamed. Apparently not absorbing the Computer’s insult. Probably for the best.

“Now silence! I need to concentrate.”

The Computer remained silent as he watched Zim work. Zim's hands worked efficiently at a pace that showed he was comfortable making these types of repairs.

Even so, an automatic repair would be faster and more efficient. The Computer took into consideration the stress patterns in his voice and heart rate when he thought he needed an automatic repair. In addition to his reluctance to being scanned or his PAK being scanned.

…...So, he knew he was defective then?

That had to be the logical conclusion. Only Defectives tended to get nervous about PAK fiddling or PAK repair. Although, observing his Master's hands, Zim had no qualms with repairing himself. Due to his intense focus and efficiency, it could almost be described as therapeutic for him.

Then was it the Computer himself he was afraid of?

There was still too much insufficient data for him to make a logical conclusion at the moment. But he will take Zim's comfort in mind when he eventually needs to consult him about PAK and biological repair in the future. Because let's face it, Zim will hurt himself again.

Heres a wip of a sequel.

Dmviolence, by jade

Hello, if youre hearing this, it probably means im dead. Either that, or im alive and just got tired of keeping this hidden. You might remember my voice from a previous recording about a takeover in sector ⬽:➻, in which id helped prevent total annihilation of the sector. At the time i was unnamed, however now you may call me Kalton. After the takeover i resigned and moved to a job at a dmv. This planet was, for some reason, in one of the most tactically advantageous locations in the galaxy. And for some reason the higher ups dedicated the whole damn planet to dmvs. Dont ask why. Now, onto the story.

I woke up, and i put on my emerald green contact lenses. Just like any other day. I put on a basic white t-shirt and a leather bomber jacket along with a pair of jean shorts. If you cant tell by now, im gay.

I live in a small apartment. By small apartment i mean a bedroom, a bathroom and a kitchen all crammed into 2 rooms. I hopped out the bedroom window onto my motorcycle. It was a diamond white motorcycle with deep red stripes along the sides and the handlebars. My pride and joy. I put on my jet black helmet and took off towards my job at the, you guessed it, dmv.

Chapter 2

I pulled up in the parking lot and took off my helmet, my blue hair a total rats nest. The doors were push doors, yet i somehow ALWAYS pulled first. I entered the dmv and went to my station. A few hours passed by and no one had come in yet, which was unusual. So naturally i decided to sit down on the floor, put in my earbuds, and enjoyed some heavy metal. A few more hours passed by, and usually by now i wouldve been yelled at by my boss. This struck me as odd so i stood up. I really wish i hadnt stood up. The place had been completely destroyed. There were drop pods crashed in through the roof and they all had the ERGON logo on them. Ergon was a multi trillion dollar pencil manufacturing company with its own military. They had previously tried to take over sector ⬽:➻ when i had been working there. I was not looking forwards to what was about to happen.

Quickly, i ducked back onto the floor before anyone saw me. There were 4 riot soldiers holding this building. This was gonna be fun. The riot soldiers are your stereotypical riot gear and police baton soldiers. But these guys had laser batons and the riot gear gave them heightened strength and speed. They also had some, dare I say, shitty energy pistols. I crawled over to one of the soldiers who wasnt being watched and broke their neck. Carefully I took the baton and the pistol. Slowly crawled my way back to my station and checked the shot count in the pistol. I had 6 shots, just enough to take care of the remaining three soldiers. I stood up quickly and shot each soldier twice in the head. First shot to open the riot helmet, second shot to kill. I vaulted over the counter and grabbed the three pistols. These things were so stupid. You couldnt even remove the clips. Once you ran out of shots, the pistol was useless. Nonetheless, i didnt have any choice. I had a laser baton and 18 total shots in 3 pistols.

Upon leaving the building, my motorcycle was one of the few things to survive. It had alot of scratches and damage, but it still worked. The helmet was shattered however. I mounted the motorcycle and took off towards the next closest dmv. Maybe id find some better gear there.

Chapter 3

Pulling up next to the second dmv i immediately noticed 3 things. 1: there was blood everywhere. 2: there were 25 soldiers here. And 3: they all had energy weapons. The reason these things are relevant is because energy weapons dont cause bloodshed. This was the result of something else. Something new i hadnt dealt with yet.

I drove up and ran over 5 of the soldiers. This was probably an incredibly bad idea, seeing as i had 18 shots, enough for 9 kills, and there were 20 soldiers left. Every single soldier turned to me and i, being the absolute genius that i am, welded the front of one of the pistols shut with the laser baton, shot it off, and threw it into thei crowd of soldiers. It exploded, releasing a shockwave of energy and disabling the soldiers. I then used the baton to cut through the riot gear and kill the soldiers. I felt like a badass. That is until a mechanical looking wolf jumped at me and started trying to rip my face off.

The wolf was a frostwolf, except it had been placed into a mechanical frame and its teeth and claws had been replaced with lasers. I tried to bash it off of me with the baton but it just bit it in two. This gave me just enough time to grab an energy pistol and shoot the wolf. It kept trying to kill me amd i wasted a whole clip on it until suddenly, the dog started to levitate in the air and got thrown aside into a wall. I got up and was instantly frozen in place. Thats when.. she walked up.

Chapter 4

The she i am reffering to is ebony. A goth/punk wannabe with light blue tear shaped eyes and black hair with purple streaks. Shes a bitch whos mind got too powerful and now she can move things without touching them. Shes been chasing me for months. Not in a murderous way. Shes just obsessed with me. Ive tried to tell her im gay but she wont listen. And now im at her mercy.

She walked up to me and kissed me on the cheek. I hated it. She looked as if she was contemplating whether or not to free me when a pod came down from the sky and crushed her. Thank god. But i honestly wouldve rathered suffered at her hand than deal with what i had to deal with next...

Out of the pod came the warden. The goddamn warden from sector ⬽:➻. Last id seen him hed been in the same situation as ebony. Crushed to death under a pod. But this time, instead of being on my side, he was here to kill me. He was huge. Like seriously huge. He was at least 8 feet tall and shaped like gaston. Whos gaston? Nobody knows these days. But its basically a way to say "extremely buff and wide". Back to the story. The warden wasnt looking very good, considering the rotten skin, obviously quickly patched together face, and muscles hanging loose out of his skin. His rotting ruined body was held together by an exoskeleton of chromium-tungsten alloy. Nothing i had was gonna cut through that. I was gonna have to get creative here..

The warden had 2 weapons, both of them were his fists. Huge gauntlets that were each about the size of a cow. Definitely bigger than his previous set. They were a golden green metal i couldnt identify. But i didnt want to get hit with one to try and find out. I ran. I ran as fast i could run into the dmv and hid. I could hear the wardens footsteps. It was as if a small earthquake happened each time he took a step.

I peeked over the desk i was hiding behind and saw him punch through the 2 desks opposite to me. It took no effort and i couldve sworn i saw him smile. Obviously i didnt. Cause he didnt have a mouth anymore. But if he did, he definitely wouldve smiled. I took a shot to get his attention and ran off towards the wall. The warden was definitely faster than i expected.

Luckily i managed to dodge the blow by a centimeter. The metal smelled of decaying flesh and popcorn. The wardens blow punched a huge hole in the wall. I hope you see where im going with this.

I ran off to another wall and we repeated this same process a number of times until the building was barely still up. I ran out the doors and threw the baton at the last of the supports, cutting through it and causing the building to collapse in on the warden. He wasnt getting out of that. I decided to search the rubble to see if i could find anything worth taking. I found a new baton, a flame rifle and a few more energy pistols.

The flame rifle was a very interesting design. The sides were painted jet black with flame decals scattered about. You could feel the heat on the inside and it made the gun warm to the touch. Comfortable to hold. Other than that though, it looked like an old fashioned 8.59mm sniper rifle. It had 4 shots remaining, so id have to use it sparingly.

I grabbed some scrap materials out of the rubble to make a holster for it and put it on my back.

The energy pistols just dangled from a keychain. The baton was simply turned off and placed through a hole in the back pockets of my shorts. I ran to my motorcycle and drove off, i needed to find out more. I had questions, and i had a sneaking suspicion that i knew where to find the answers.

I drove off again, i was dirty and there was blood on me and my bike. I probably looked like a serial killer. But i knew that if anyone was still alive, itd be jayden. They were.. well. They were a vampire. They lived in a swampland area and wore sparkly rainbow shirts and a huge sunhat. The sunhat allowed them to go outside in the sun, and they only drank coconut water. They also had a crazy amount of weaponry and used to work at ergon, before being fired for stealing weaponry. By the way, if you havent noticed by now, im using they/them to refer to jayden. Jayden doesnt have a gender. Jayden.. is kind of my crush. It probably has something to do with the fact that theyre the only person on this planet who talks to me. Other than ebony.. but ebony is... not my type i guess. Anyways, back to jayden. Jayden was on the roof of their swamp shack drinking coconut water out of a wine glass. I yelled up at them and they fell off the roof onto my back. I guess i cushioned their fall. Jayden immediately said "What do you need dear" without waiting for me to stand up, and shattered the wine glass. I informed them of the situation and asked the questions i had. Things like "what are the ergon soldiers defences like on their ships" and "how did they reanimate the warden" they had answers.

Jayden told me about the new security measures that had been put in place since id last been on an ergon ship. There was now a code for each teleportation pod and the gaurds had doubled. As for the warden, it turns out jayden was actually the first test run in reanimation sciences, and couldnt answer me because they had been unconcious in a lab when the warden was reanimated. That explained the vampire undead thing. Jayden invited me into the shack where they pulled a nail out of the floorboards and it turned into a ramp to the basement. Down in the basement? Thats where jayden kept their weapons they stole. And boy oh boy were there some interesting ones.

One that immediately caught my attention was the big rocket launcher. It had 3 barrels and each was a different colour, indicating a different effect. One was red, one was yellow, and one was green. The red barrel fired a normal explosive rocket, the yellow barrel fired an electromagnetic pulse rocket, and the green barrel fired an acidic explosive. And the launcher shrunk down to the size of an energy pistol when a button was pressed. It gathered up dirt and dust and garbage around it from the back to quickly convert into ammo but the only downside is that it would be difficult to use more than once in an area.

Jayden picked out an old shotgun. At first i didnt understand why, but then they loaded the clip. The clip was a huge drum that loaded in the bottom of the barrel. The drum was see through and inside you could see sawblades lined up side by side. When they pumped the shotgun a blade got lifted into a slot between the 2 shotgun barrels and started glowing red. When the trigger was pulled, the blade spun at high speeds and fired out of the slot, spinning along the ground like a wheel. It could cut through anything a baton could cut through and seemed to almost follow its target. The gun itself looked like an DP-12, except behind the pump, a large clear drum full of sawblades was in place. The blade sat between the barrels in place of the iron sights and got heated up by an electrical circut.

I also took a laser sword instead of my baton, it was just like the one that [3825968] had, except this one was about an inch longer. The final weapon i took was an acid thrower. It was basically just a watergun with acid in it. Ive always been partial to acidic weapons. If youve heard my other story, youd know why..

Jayden also took a submachine gun that fired freezing rounds. The rounds were essentially glorified waterballoons with liquid nitrogen in them. Though the rounds were bullet sized, enough shots from it would certainly freeze you in place. The freeze gun was about the size of the average human head, and was painted navy blue with blue saphire stripes placed along it. We both left the shack, me with my sword and jayden with a wine glass. We were ready to kick ass and put a stop to this.

We left and immediately both got flung into some trees. Guess who it was. It was ebony. Her body had been found and reanimated. I was starting to see a pattern. And now we had to fight the telekinetic who could kill us with a wave of her hand.

She was levitating. Her eyes were glowing red and her hair was floating in the air. She had a smile of someone about to rip your arms off and beat you with them. I tried to take a shot at her but my hand got knocked aside by an invisible force. So i tried the next best thing. Seduction. Fake seduction. Hopefully the whole dying and coming back from the dead thing didnt make her stop being weirdly obsessed with me.

While i faked surrender and complimented ebony and attempted to seduce her, jayden took aim of their ice gun and shot a burst at ebonys right arm. The arm froze in place and shattered. Hopefully that would lower the strength of her telekinetic abilities. It did. But only by about half. Which meant jayden got thrown into the air as i tried to discreetly unholster my acid gun. It wasnt discreet enough and the gun was knocked from my hand.

The gun flew forwards and the impact of hitting the ground set it off for a second, just enough to spray an acidic burn through her arm. Incapacitating her. Jayden ended up sneaking up behind her and impaling her through the skull with the shattered end of their wine glass. Finally ebony was dead for good.

The acid gun was busted, so we had to leave it behind. We got onto my motorcycle and took off towards my apartment building. We would need food if we were going to be traveling. An apartment complex would probably be full of foods, and alot of dead people who wouldnt care if we took some stuff.

Application of high power semiconductor lasers welding

With the development of laser processing technology, high power semiconductor lasers have gradually emerged, and are regarded as a new generation of laser light sources together with fiber lasers, ultrafast lasers, disk lasers, etc., making many important applications possible. Listen to High power semiconductor lasers exporter Dershine to explain the application of high power semiconductor lasers welding for you.

Compared with other lasers, high power semiconductor lasers have incomparable advantages, such as small occupied space, simple structure, stable system, and long service life; uniform energy distribution, high photoelectric conversion efficiency, and high light absorption rate of metal materials It realizes the characteristics of automation and is widely used in metal material processing.

High power semiconductor lasers have been widely used in metal material welding due to their excellent performance. Because of its large light spot, uniform beam quality distribution, and high absorption rate of metal materials, the molten pool is stable, with no spatter, and the weld surface is smooth and beautiful during the welding process. welding.

1. Laser spot welding, seam welding

The semiconductor laser spot welding process is thermal conduction welding, which is achieved by adjusting the laser power and radiation time to melt the metal material. Due to the uniform distribution of the spot energy, the laser energy can be slowly decreased and the gradient can be realized, thereby solving the problem of porous porosity caused by the collapse of the pseudo-keyhole at the end of the spot welding seam.

2. Laser continuous welding

The semiconductor laser can form a keyhole effect in the continuous welding process and has a strong penetrating ability. In continuous thermal conduction welding, the welding process is stable, the surface is smooth, the shape is beautiful, and the welding seam section is semi-circular, which can realize the welding of metal sheet structural parts (butt welding, lap welding, fillet welding, etc.), and the welding seam width can reach 3.5mm; during continuous deep penetration welding, the welding process is stable, spatter-free, and the weld section is Y-shaped. The strength after welding can meet the requirements of the workpiece.

3. Double beam laser welding

COMPARISON OF PROCESSING METHODS FOR DEFORMED STEEL STRUCTURES

I believe that many small partners will have a question in their minds when they see steel structure buildings of various shapes, that is, how these special-shaped steel components are produced.

In terms of technology, there are three forming processes for special-shaped steel structures, cold bending, hot simmering, and direct special-shaped welding.

Cold bending is a metal working method. A sheet of metal material is mechanically bent into a shaped profile at room temperature. The advantages of OEM Steel Profile for Building cold bending are: It can produce various special shape steel profile for sale ultra-thin, ultra-wide and complex shapes that cannot be produced by rolling; its characteristic is to save metal materials. The mechanical properties of the product are good. Commonly used processing methods are roll bending, pressing, drawing and bending.

Hot Simmer Bend

Hot simmer bend has also become "hot simmer bend". As the name suggests, it is mainly formed by external mechanical force after heating the steel pipe. The heating method is that the high-frequency electromagnetic OEM Steel Profile for Building coil heats the steel to 800° through the oscillating magnetic field. At this temperature, the strength of the special shape steel profile for sale steel is reduced by 90%, which is convenient for mechanical forming, and there is no residual stress after forming. Section steel can also be processed into special shapes by hot bending.

Direct Special-shaped Welding

Direct special-shaped group welding, as the name implies, is to directly cut the steel plate into a special-shaped shape, or to make the steel plate into an arc shape through a roller and directly weld it. The loss of this processing OEM Steel Profile for Building method is much larger than the loss of the first two methods, because the special shape steel profile for sale steel entering the site is mainly a plate, with a width of about 2.1 meters and a length of 9-12 meters. If you cut the material according to the arc as shown in the figure, the loss can be imagined. However, direct special-shaped group welding also has its advantages, especially in bridges and large steel structures, when the thickness of the plate reaches 40mm, it is difficult to ensure that it is processed into an ideal geometric size by machining, so direct special-shaped group welding is required.

Analysis of Advantages and Disadvantages of Three Processing Methods

As mentioned above, cold bending has the best economic performance and the worst mechanical energy, because it does not require thermal processing and does not increase the loss, but this processing OEM Steel Profile for Building method can only be used for components with thin plate thickness, because the OEM GI steel profile for sale plate If the thickness is too large, the general machine cannot be pressed and will generate large residual stress. The economics and mechanical properties of hot simmer bending are intermediate, it can process thicker plates, and most of the residual stress will be eliminated after heat treatment. Direct special-shaped group welding is the worst economical but the best mechanical performance, because direct OEM GI steel profile for sale special-shaped group welding will produce a lot of scraps, and special-shaped group welding does not mechanically process the steel plate, and will not generate additional participating stress, and direct special-shaped group welding Group welding is not limited by the thickness of the steel plate.

At WORTHY HARDWARE CO.,LTD, our experienced staff and state-of-the-art machines empower us to supply exact comes about on time each time.

Classification and use of stainless steel

1.304 stainless steel. It is one of the foremost broadly utilized austenitic stainless steels. It is reasonable for the make of deep-drawing shaping parts and corrosive channels, holders, auxiliary parts, different instrument bodies, etc. It can moreover fabricate non-magnetic, low-temperature hardware and portion.

2.304H stainless steel. The inner department of 304 stainless steel features a carbon mass division of 0.04%-0.10%, and its tall temperature execution is superior than that of 304 stainless steel

3.304L stainless steel. The ultra-low carbon austenitic stainless steel created to illuminate the genuine intergranular erosion propensity of 304 stainless steel due to the precipitation of Cr23C6 beneath certain conditions, its sensitized state of intergranular erosion resistance is altogether way better than that of 304 stainless steel. But for the somewhat lower quality, other properties are the same as 321 stainless steel. It is primarily utilized for corrosion-resistant hardware and parts that cannot be solid-solution treated after welding, and can be utilized to make different instrument bodies.

4.316 stainless steel. Molybdenum is included to the 10Cr18Ni12 steel to form the steel have great resistance to decreasing media and setting erosion. In seawater and other different media, the erosion resistance is superior than 304 stainless steel, basically utilized for setting erosion safe materials.

What Are The Types Of Liquid Cold Plates?

The increase in heat load of high-power electronic equipment and the requirements of product sealing performance have changed the traditional design thinking, and liquid cooling has become the mainstream trend. Compared with traditional air-cooled radiators, liquid cooling plates have significant performance advantages, especially in high-power equipment and high heat flux. Each product has its advantages, depending on the design of the liquid cold plate, the choice of coolant, the pressure drop requirements and the customer's budget.

Liquid cold plate is currently used in: renewable energy systems, medical equipment, IGBTs, lasers, data centers, industrial power supplies, defense systems, avionics, battery cooling, etc.

Buried cold plate

Buried pipe cold plate is the simplest form of cold plate, just embed the pipe in the base plate. According to the required thermal performance and coolant, copper or stainless steel tubes are generally used. Use CNC equipment to process pipe grooves on the substrate, embed the pipe into the substrate, and pour the epoxy resin pressure table, or weld in the appropriate position, which can maximize the service life and thermal performance.

Deep hole drilling cold plate

The deep hole drilling cold plate drills a series of holes on the aluminum plate to form multiple flow paths. First determine the inlet and outlet fluid paths, and then drill some holes perpendicular to the main fluid path, and then block some of the holes to form a continuous coolant path. The advantage of this kind of cold plate is that there is no thermal boundary in the manufacturing process, and the aluminum plate has no thermal stress, so it is easier to achieve flatness.

FSW friction stir welding cold plate

The FSW friction stir welding cold plate is constructed by a base plate and a cover plate. On the base plate, CNC is used to add a liquid flow path groove, and then the cover plate is placed in the groove above the flow path, and FSW (Friction Stir Welding) ). Finally, flatten the welding surface by flashing, and add inlet/outlet holes and component mounting holes.

Die-cast cold plate

Die-cast cold plate is a two-piece structure, suitable for complex large-capacity liquid cold plates. Multiple internal and external metal parts can be combined into two die casting tools. After casting, the two die-cast parts are bonded together by welding or using epoxy resin.

Brazing cold plate

Brazing cooling plates are usually used in designs that require low thermal resistance and high performance. This type of cold plate has great flexibility in design, such as thermal resistance, heat flow, pressure drop, fluid path, size, shape, material hardness, surface geometry, and installation of components on both sides of the plate. The interior can be completed by processing the deflector and heat sink from the base material, or by introducing high-performance corrugated aluminum fins, and then brazing these parts together.

Dip Soldering Cold Plate

The components are preheated in an air furnace to ensure that the temperature of all components is uniform, and then the parts are immersed in a molten salt bath. The molten flux is in contact with all inner and outer surfaces at the same time. This liquid is heated very quickly and evenly. The molten pool is a flux, so it can be completely bonded on an oxide-free surface. The immersion time is determined by the object to be heated, but the duration rarely exceeds two minutes.

Vacuum brazing cold plate

Brazing in a high-vacuum environment can control the brazing process to the greatest extent, and any oxidation or fouling phenomenon is the first choice for aerospace components, medical equipment and application equipment with high requirements on parts.
