C18150 RWMA RESISTANCE SPOT WELDING TIP ELECTRODES
C18150 RWMA RESISTANCE SPOT WELDING TIP ELECTRODES
Resistance spot welding tip electrodes are a process that involves joining two metal surfaces by applying heat and pressure to a small area. The heat is generated by an electric current that flows through the metal surfaces, and the pressure is applied by two electrodes. The material of Resistance spot welding tip electrodes are made by C18150 RWMA Class 2 Chromium Copper Alloy. Kojako Vietnam is a leading manufacturer and provider for the Resistance spot welding tip electrodes in Vietnam.

APPLICATION OF C18150 RWMA RESISTANCE SPOT WELDING TIP ELECTRODES
There is a plethora of material types that are excellent choices for spot welding applications. The material is not limited to pure metals only. Alloys are also excellent for this. In fact, steel has the widest level of utilization of spot welds because of its use in the automotive sector. Generally, any metal alloy with high electrical resistance can be an excellent choice. When it comes to materials that don’t work well with the process, Aluminum and galvanized steel are the most prominent ones. Both materials require a significant intensity of the currents, which can hinder the formation of the weld. Apart from the type of material, it’s also important to ensure the appropriate thickness of the sheet metal. Generally, the most appropriate thickness is around 3mm, which can give the best quality weld. Apart from that, the two sheets to be fused should be of the same size or have a 3:1 size ratio for the most optimum results.
Spot Welding for Different Industries
The spot-welding process has a variety of applications across various industries. However, the following 4 industrial areas rely the most on this technique for the best quality products.
Electronics Industry
Circuit boards, gas sensors, and solar panels are some of the most common components that rely on spot welding to ensure quality and efficiency in production. Moreover, this welding process is also ideal for the most complex electrical components with intricate details as the weld remains concentrated on a single point and allows ample space for other capabilities and processes.
Automobile Industry
Naturally, the automobile sector has the most common use of spot welding because a major chunk of any car’s body comprises sheet metal. This welding process is cost-effective, efficient, and doesn’t require any elaborate setup. Resultingly, it can be integrated into any assembly line, which makes it among the most suitable processes for automation.
Join Rolls of Nails
Spot welds are excellent for the process of creating nails. The welding process creates faster nails with automation when compared with a pneumatic nail gun.
Manufacturing Batteries
As stated before, spot welding is an ideal choice for the manufacturing of batteries. Batteries have several interconnected terminals that use sheet metals for partition.
