E: The 1st letter, "E" stands for a welding electrode.

1st two digits: Elaborate the minimum tensile strength of produced weld metal expressed in KSI (kilopounds /square inch) (MPa/10). In this case, "70" means 70 KSI or 70,000 PSI (pounds/square inch).

3rd digit: Elaborate the recommended welding position. The number "1" means it is an all-position welding electrode. "2" is used for horizontal & flat positions. 3 is for a flat position & 4 allows for all positions but limits vertical travel downwards only.

4th digit: Elaborate the flux coating and the type of current required. The current can be alternating, direct current electrode positive or direct current electrode negative. All coating types for mild steel weld electrodes are in the table below.

Additionally, if the electrode has the letter "M", like E7018M, it elaborates that it is designed to meet most military needs. It has hi-toughness, low moisture content and effectively diffusible hydrogen limits.

If the electrode has the mean "-1", like E7018-1, the welding electrode meets the need for improved ductility and toughness.

A mean of "HZ": E7018HZ, specifies that the welding electrode meets an optional supplemental test for hydrogen diffusion. These electrodes are safe when max hydrogen diffusibility is a must.

2. Select according to base metal:

While selecting an electrode, make sure it is compatible with your base metal.

Mild Steel: The best welding electrodes for mild steel are E6013 and E7018. These make your welding strong and durable.

What are Welding Rods?

Welding rods, also known as welding electrodes, are thin metal rods that are used to join pieces of metal together through welding. The rods are made of wire that contains a core of flux, a deoxidizing and cleaning agent. The flux displaces impurities and prevents oxidation during the welding process.

During welding, an electric current is passed through the welding rod and creates an arc between the rod and the metals being joined. This generates heat up to 6,500°F, which melts the rod and the base metals. The melted metals mix together and cool to form a permanent bond. The flux also produces an inert gas shield around the weld pool to prevent contamination.

There are many different types of welding rods available for various metals and welding processes. Some common examples include:

Carbon steel rods - For joining carbon and low alloy steels. Most versatile and widely used.

Stainless steel rods - For welding stainless steel and preventing corrosion. Require shielding gas.

Aluminum rods - For aluminum and aluminum alloys. Coated to prevent oxidation.

Nickel alloy rods - For high temperature alloys, heat resistance and corrosion resistance.

Cast iron rods - For cast iron repair and joining. Have high carbon and silicon content.

Hardfacing rods - For wear resistance and building up surfaces. Made of high carbon or alloy steel.

Welding rods were first developed in the late 1800s as bare wire electrodes. Coated flux electrodes emerged in the early 1900s, improving arc stability and metal protection. Further advancements led to specialized rods for different materials. Today, welding rods continue to evolve alongside welding technology and materials.

Carbon Steel Rods

Carbon steel rods contain between 0.1-0.3% carbon. They are very common and versatile general purpose welding rods suitable for many applications.

Applications and Uses

Structural fabrication

Construction projects

Automotive industry

Manufacturing and general repairs

Carbon steel rods are suitable for welding most steels, particularly low carbon and mild steels. Their versatility and low cost makes them one of the most widely used welding rod types.

Properties and Characteristics

Tensile strength around 60,000 psi

Good ductility and impact strength

Prone to rusting unless protected by paint, primer or zinc coating

Medium hardness - around Rockwell B70-90

Can be used in all welding positions

Carbon steel rods are easy to strike and have good slag removal. The weld deposit is softer than the base metal, making it less prone to cracking. The smooth arc action provides good weld bead control.

Recommended Welding Techniques

Shielded metal arc welding (SMAW)

Gas metal arc welding (GMAW)

Flux cored arc welding (FCAW)

Carbon steel rods work well with direct current electrode positive (DCEP) polarity to provide a deep penetrating arc and smooth weld deposit. Short arc or globular transfer MIG welding works best for positional welds. Use stringer beads on thin materials and weave beads on thicker sections. Preheating is recommended for very thick materials to prevent cracking.

Stainless Steel Rods

Stainless steel rods offer excellent corrosion resistance and durability, making them a popular choice for many welding applications. They contain chromium which forms an invisible passive layer of chromium oxide when exposed to oxygen. This prevents corrosion and rust.

Applications and Uses

Stainless rods are used for welding projects that require weather and corrosion resistance like chemical tanks, food processing equipment, boat railings, architectural features, and structural components in coastal areas. Common types include 308 and 316 stainless steel. 308 has good corrosion resistance while 316 offers higher chromium content and greater resistance to saltwater.

Stainless rods can join thin sections without burn-through and withstand high heats. They are ideal for stainless to stainless welds but can also join stainless to mild steel if proper precautions are taken.

Welding Considerations

Stainless rods should be kept dry before welding to prevent hydrogen contamination that can lead to cracking. It's important to thoroughly clean the base metal, removing any oils, paint or coatings from the weld area.

Use DC electrode positive (reverse polarity) current for most stainless welds. Argon-rich shielding gas protects the puddle from atmospheric contamination. A grinding disc dedicated to stainless prevents carbon steel cross-contamination. Slow travel speeds and low heat input help ensure a quality weld.

Techniques

The most common techniques for stainless steel welding include GTAW (TIG), GMAW (MIG) and SMAW (stick welding). GTAW produces the highest quality welds for corrosion resistant applications. MIG welding with a tri-mix shielding gas blend allows faster travel speeds. Stick welding can be done but requires more skill to control heat input. Proper joint design and fit up helps compensate for the low thermal conductivity of stainless.

Aluminum Rods

Aluminum rods are commonly used for welding aluminum alloys in applications where strength and low weight are priorities. Aluminum has become increasingly popular in automotive, aerospace, transportation, and construction applications due to its high strength-to-weight ratio.

There are a few important considerations when welding aluminum:

Aluminum conducts heat very quickly, so it requires high amperage for welding. AC current is typically used since it provides a stable arc.

Aluminum oxide on the surface can interfere with weld quality, so the oxide layer needs to be removed in the weld area. This is done through mechanical cleaning or chemical etchants.

Filler rods need to match the base alloy being welded. 5000 and 6000 series aluminum alloys are most commonly welded. 4043 and 5356 rods are frequently used.

Shielding gas (usually argon) prevents oxidation during welding. Gas metal arc welding (MIG) is a common technique for aluminum.

Preheat is often unnecessary for thinner aluminum but helps prevent cracking in thicker sections. Slow cooling also reduces cracking.

Proper preparation, matched filler material, sufficient amperage, and shielding are critical for successful aluminum welds. With the right technique, aluminum can be welded with results equaling or exceeding the strength of the original base metal.

Nickel Alloy Rods

Nickel alloy rods are commonly used for welding high-strength alloys exposed to extreme temperatures, pressure, and corrosion. They are ideal for applications that demand heat and corrosion resistance like power plants, chemical processing equipment, and marine components.

Some key properties and advantages of nickel alloy rods include:

High strength at extremely high temperatures up to 2000°F. Nickel retains strength and toughness in high heat.

Outstanding corrosion resistance. The nickel content resists corrosion from acids, alkalis, salts, and other chemicals. This makes it well-suited for equipment exposed to seawater, acids, solvents, and more.

Heat and thermal fatigue resistance. Nickel alloy welds resist cracking even when repeatedly heated and cooled during thermal cycling.

Oxidation resistance. Forms a protective oxide layer that prevents erosion at high temperatures in air or gas environments.

Nickel alloy rods are used with nickel-based filler material matching the base metals. Common nickel alloys used for welding include Monel, Inconel, Hastelloy, and Incoloy. GTAW (TIG) welding is most commonly used since it allows for control of heat input. Other techniques like GMAW, SAW, and FCAW may also be used.

Proper storage and handling is important to avoid moisture absorption which can lead to weld defects. Best practices include storing rods in a heated oven and thoroughly drying rods before use. Precise welding techniques help avoid cracking and ensure optimal properties.

Cast Iron Rods

Cast iron rods are used for welding cast iron components. Cast iron has a high carbon content, making it more brittle and prone to cracking during welding.

When welding cast iron, preheating is essential to prevent cracking. The cast iron should be preheated to 300-600°F depending on thickness prior to welding. Slow cooling after welding, either in still air or using an insulating blanket, is also important to prevent cracks.

Cast iron rods contain more alloying elements like nickel and copper to improve strength and crack resistance. The deposited weld metal has a composition designed to match the cast iron base material.

The technique for welding cast iron is also important. Stringer beads should be used instead of weave beads, as the latter produces more shrinkage stress. Short welds of 1-2 inches should be made at a time, allowing periods of cooling between passes. Care should also be taken to avoid melting through the base metal.

Proper welding technique, preheat, and rod selection can help mitigate the cracking risks when welding cast iron. The welder must understand the unique properties and demands of cast iron as a base material. With the right approach, quality welds can be made on cast iron components.

Hardfacing Rods

Hardfacing welding rods are used to build up thickness and increase wear resistance on metal surfaces that are subject to abrasion, impact, erosion, galling and other wear mechanisms. They allow you to apply a hard, wear-resistant weld overlay on top of the base material.

Some typical applications where hardfacing rods come in handy:

Earth moving and mining equipment - loader buckets, bulldozer blades, excavator teeth, etc. The constant abrasion calls for a durable wear layer.

Agriculture and construction equipment - plowshares, cultivator sweeps, grader and snowplow blades. Hardfacing withstands the punishment of abrasive soils and rocks.

Industrial processing equipment - rock crushers, pulverizers, hammer mills. The crushing and grinding action demands surfaces that won't degrade easily.

Conveyors, chutes and hoppers in material handling systems. The sliding and impact of rocks, ores, etc leads to wear. Hardfacing provides a protective buffer.

Drill bits and cutting tools for machining and boring. The friction and cutting forces require tools to have a hard, abrasion-resistant working edge.

Valves, pump shafts and impellers handling abrasive fluids. Hard particles in liquids can quickly damage unprotected surfaces.

Steel mill rolls for forming and drawing wire, rod and sheet. The extreme pressures call for durable roll surfaces.

When applying a hardfacing overlay, proper technique is crucial to getting good results:

Prepare the base metal surface by removing any dirt, oil, rust or other contaminants. Grind a slight chamfer or groove to improve bond strength.

Use a stringer bead technique, depositing side-by-side beads rather than weaving. This prevents excess dilution of the hardfacing alloy into the milder base metal.

Maintain a low heat input. Too much heat can burn away hard carbides or form brittle microstructures in the weld zone. Use maximum current settings below 150 amps.

Peen each weld bead while still hot to relieve stresses. This prevents cracking which can lead to poor wear resistance.

Build up multiple layers, allowing the previous bead to cool between passes. Follow the recommendations of the electrode manufacturer.

After welding, allow the overlay to cool slowly and soak for a few hours before puting into service. This prevents untempered martensite which is prone to cracking.

With the proper electrodes and technique, hardfacing provides superior abrasion and wear resistance that can significantly extend equipment service life.

Brazing Rods

Brazing is a metal-joining process similar to soldering and welding. The key difference between brazing and welding is that brazing does not melt the base metals. Instead, a filler metal with a lower melting point is used to join the base metals.

Some key properties and uses of brazing rods include:

Brazing rods contain filler metals like copper, zinc, and silver that have lower melting points than steel or aluminum. When heated, the filler metal melts and flows into the gap between the base metals, joining them together.

Brazing allows joining of dissimilar metals like steel and copper that cannot be welded together. The base metals do not melt, so there are no issues with metallurgical incompatibility.

Brazed joints have excellent thermal and electrical conductivity and can withstand high operating temperatures. This makes brazing suitable for joining metals in applications like heat exchangers.

Brazing produces smooth, clean joints without the sputtering or spatter associated with welding. This gives brazed assemblies a neat professional finish.

Common brazing filler metals include bronze, brass, silver, and nickel alloys. The filler metal composition can be chosen to match the base metals being joined.

Brazing has applications in automotive parts, jewelry, plumbing fixtures, aviation components, and other metal fabrication. It provides strong, durable joints for assemblies and subassemblies.

Overall, brazing produces strong joints by melting and flowing a filler metal into the gap between close-fitting parts. The process avoids melting the base metals, enabling dissimilar metals to be joined.

Flux Coated Rods

Flux coated welding rods have a coating applied to the outside of the electrode rod to protect the weld from oxidation and contamination. The flux coating serves several key purposes:

Purpose of flux coatings:

Flux coatings provide protection from atmospheric contamination during the welding process. They generate a protective gas shield around the arc and molten metal to prevent oxidation. The flux also forms slag, which floats to the surface of the weld metal to further protect it as it cools.

Types of flux coats:

Common types of flux coatings include rutile, basic, cellulosic, and acid flux coatings. Rutile flux rods are versatile and work well for many general purpose welding jobs. Basic flux creates deep penetration welds on metals like steel. Cellulosic flux is used for welding vertically or overhead. Acid flux is used on stainless steel or nickel alloys.

Benefits for welding:

Flux coatings improve the flow of metal, stabilize the arc, and allow for out of position welds. They enhance the strength and aesthetic quality of the weld by reducing porosity and preventing contamination. Flux also helps start the arc easily and provides a smooth arc characteristic. The slag produced can be easily chipped away after cooling to reveal a clean weld.

Safety and Best Practices

Welding can be dangerous if proper safety precautions are not taken. Here are some tips for safely handling welding rods and practicing good technique:

Proper Handling and Storage

Always wear thick, dry welding gloves when handling welding rods to avoid burns. The coating on the rods can be hygroscopic and absorb moisture from your hands.

Store rods in a dry place and check for rust or moisture absorption before use. Discard any wet or damaged rods.

Return unused rod stubs to their original package to avoid mixing alloys. Different alloys and coatings require different amperages.

Avoid hitting or dropping rod packages to prevent damage to the rods. Cracks in the coating can lead to poor welds.

Welding Safety Gear

Wear a welding helmet with the appropriate lens shading for the amperage used. Lighter shades like #10 are for lower amperages under 100A. Darker shades like #14 are for higher amperages over 200A.

Use heat-resistant gloves, an apron, and long sleeve shirts to protect against burns and UV exposure. Leather gloves and cotton/wool clothing are preferred.

Wear safety glasses under your helmet and close-toed shoes on the shop floor. Use earplugs or earmuffs to protect hearing.

Technique Tips for Quality Welds

Keep the arc length consistent during the weld. Arc length is the distance between the rod tip and base metal. A short arc will produce a wider, flatter bead while a long arc makes a narrower, taller bead.

Use the appropriate welding angle and travel speed to ensure good fusion with the base metal. Push the rod slowly and steadily in the direction of travel.

Chip away slag and clean each weld pass before applying the next. Slag trapped against the metal can cause defects.

Avoid arcing or scratching the rod coating when striking the arc. Damaging the flux coating can result in poor weld quality.

Make sure you're using the correct amperage settings for the rod size and alloy you've chosen. Follow manufacturer recommendations.

GI Plate Electrode:

A GI plate is another common type of earthing electrode. It is usually buried horizontally in the ground. The size of the plate is determined based on soil resistivity and the specific requirements of the grounding system.

GI Strip Electrode:

Similar to the GI plate, a GI strip can be used as an earthing electrode. The strip is buried horizontally in the ground, and its dimensions are determined based on the grounding system requirements.

GI Electrode with Backfill Compound:

Some grounding electrodes are treated with special backfill compounds to enhance their conductivity and reduce soil resistivity. This helps in achieving lower resistance to earth.

Chemical Earthing Electrode:

In chemical earthing systems, a compound or mixture is used around the electrode to improve conductivity. This type of electrode is designed to maintain a low resistance value over time, even in high-resistivity soils.

Copper-Bonded Electrode:

While not made of pure GI, copper-bonded electrodes have a thin layer of copper bonded to a steel core. This combination provides the benefits of both copper and steel, offering good corrosion resistance and electrical conductivity.

Cast Iron Electrode:

Cast iron electrodes are less common but are used in some specific applications. They are durable and have good corrosion resistance.

The choice of the earthing electrode depends on various factors such as soil resistivity, space availability, local regulations, and the specific requirements of the electrical system. It's essential to consider these factors to ensure an effective and reliable grounding system. Consulting with a qualified electrical engineer or following local electrical codes and standards is recommended when designing and installing an earthing system.
