What Is An Electrical Contact?

An electrical contact is an electrical circuit component found in electrical switches, relays and circuit breakers. Each contact is a piece of electrically conductive metal. When a pair of contacts touch, they can pass an electrical current; when the pair is separated by an insulating gap, then the pair does not pass a current. When the contacts touch, the switch is "closed"; when the contacts are separated, the switch is "open".

Contacts may be operated by humans in push buttons and switches, by mechanical pressure in sensors or machine cams, and electro mechanically in relays. Contact materials are usually composed of superior conduction materials such as silver or gold. However, cheaper metals may be used to reduce costs for the main contact bump and plated with superior metals.

Contacts come in a variety of sizes, from small to very large, depending on voltage requirements and usage. Contacts are used in all types of control devices. Unlike circuit breakers, electrical contacts are not, by default, meant to interrupt a short circuit. Instead, contacts either complete or interrupt a circuit based on a secondary, low voltage control power source.  Electrical Contact Manufacturers

Modison is a leading electrical contact manufacturers facility in Mumbai that finds wide application in several industries. Modison is the only company globally manufacturing electrical contact materials and finished contacts for low, medium and high tension switch gear industry under one roof starting from silver refining to producing all the contact materials ( Ag Alloys, CuCr, CuCrZr, ETP, OFC, Cu-Ag 0.1%, CuNi2Si etc. ) by powder metallurgy or by melting and alloying – all carried out in house. 

With a commitment to maintain high level of quality Modison is having an in-house R&D dedicated team to develop and manufacture products using the best available technology and equipment for ensuring continual improvements in productivity, cost reduction and development of defect-free products.

焊機的使用壽命

　　一體化點焊機是眾多焊接工藝中無可替代切割機的重要焊接設備。其特性是： 　　1、一體化點焊機由焊鉗、焊機變壓器、焊機控制器、水冷卻系統、氣動加壓系統、(和懸掛裝置)等部分組成。結構緊湊，維修方便，體積小、重量輕，大大降低了工人的勞動強度和很大程度上節約了能耗。 　　2、一體化點焊機的電極臂采用優質鉻��銅(CuCrZr-1)，保證了焊接性能的穩定性和焊機的使用壽命及電極臂的強度。 　　3、一體化點焊機創新後，氣路系統通徑大氬焊機，再配以進口氣動元件，使焊鉗動作快捷，提高了生產效率。 　　4、焊接時，加熱時間短，熱量集中，無電弧、無火花飛濺、無焊渣、無熔焊堆積CO2焊機、焊件無熱變形。加之焊機創新後，氣路系統通徑增大，因此不僅焊接生產率高，而且能耗低(節電72、3%)，焊件外觀美，質量好。

Resistance Welding of Non-Ferrous Alloys

Following the project 

Resistance welding of nonferrous alloys (Al, as well as Cu and Ni alloys) has a number of hurdles that strengthens limits its application. For example, the oxide film of aluminium is an electrical insulator which varies with the previous history of the material. Another problem is the (too) high conductivity (both electrical and thermal conductivity) of the metal itself, especially for Al and Cu. The life of the laser electrodes is usually much lower than for steel. There are few data available on the resistance weld ingot of of nonferrous alloys (particularly for projection welding and Ni).

Innovation

Newer developments in power sources based on higher frequencies or capacitor discharge to supply more energy in shorter time, however, offer an attractive perspective also difficult weldable materials for resistance welding in a qualitative way. Customised electrode materials and sacrifice between electrode material ( "lost wire") may increase the electrode lifetime.

The use of software packages was also interesting to note for the purposes of simulation and approach of the resistance welding process. This may give the user the ability to obtain a good image in a simple way of resistance welding.

Also, two aspects scrutinised that are often underestimated wrongly. Underhand there is the influence of the nongeometric in projection welding. It was investigated to what extent an adjustment of the projection shape leads to an improvement in the quality/efficiency of the compound’s resistance welded joint

On the other hand, there are the hold-down systems which ensure that the welding lens is optimally supported during and after the welding. To this end, there have been developments that make it possible to vary the contact pressure during the entire welding cycle and thus can ensure that for example cavities are greatly reduced in aluminium alloys.

Summary of Results

Resistance welding of aluminium alloys is facing a number of problems that greatly affect the quality of the welds. Thus not only the oxide layer affects the contact resistance but also the spread of the contact resistance. Additionally, the improved plastic formability of aluminium alloys (as compared to steel, and certainly at higher temperature) ensures that the connection process is more critical (especially for projection welding). After all, when a too large plastic deformation occurs due to a too high bonding force, whether or not in combination with the welding heat, will at that location to reduce the contact force between the parts to be joined. The contact resistance in these areas is too large to form a welding lens. The welding lens will arise where the combination contact resistance / current density is lower. The exact location, the size of the welding lens diameter and whether there is or is not formed a welding lens, it, therefore, can not be certain. It is in these cases, therefore, to minimise the heat transfer as soon as possible to the welding parts and welding force, so that the plastic deformation is limited. One must also ensure that the welding time is too short so that the welding lens is given time to grow sufficiently and the bonding force is still large enough to prevent splashing. The operating range for the resistance welding of non-ferrous alloys, and aluminium alloys, in particular, is consequently considerably smaller than in steel. Some (projectile) applications are the fact that the implementation of a hardware system (suspension) on the machine table or welding head is a necessity for achieving a welded joint and/or improve the existing weld quality.

Since frequent internal imperfections were determined by the spot welding of different aluminium alloys, tests were conducted in which the effect of such imperfections on the welding lens strength was examined. For this purpose, internal imperfections in the welding lens were simulated via the drilling of holes in the middle of the welding lens. The diameter of these holes was varied from 1.5 to 3 mm. The welded test plaques were then tension (shear tension tests - longitudinal tensile tests) and compared with tensile tests on undrilled test plates. It was found that internal imperfections exert little or no detrimental effect on the mechanical properties of welded joints.

As part of this project, research was also conducted to the electrode life. For this purpose, among other things, modified electrodes (CuCrZr-electrodes is provided with a TiC-a coat off) compared to the reference electrodes (CuCrZr).
