Spot welding is different from other types of welding. There is no need to use any extra material. Two grains of metal are boiled by a classical method. Fusion is achieved by melting. The process of punting is as simple as that. Spot welding can also be called a resistance welding process. When welding, an electric current is used. Sometimes it is made using two, and sometimes more than two metals. Both pressure and heat are applied. The electrodes are copper-alloyed and are used by interacting with the metal surface. This resource is most often used in the automotive industry. It is a resistance welding process.

Welding electrodes made of tungsten, molybdenum and their alloys are particularly suitable for welding highly conductive materials such as copper. They are used in the following processes: Spot welding, Roller welding, Projection welding, Upset welding. Welding electrodes made from our refractory metals and their alloys have a relatively high level of electrical conductivity while also exhibiting outstanding stability at high temperatures. They therefore have a considerably longer service life than conventional materials such as copper and copper alloys.
