Resistance welding equipment electrode life

Resistance welding equipment, which forms a weld nugget based on resistance heat, is widely used in the field of welding carbon steel, stainless steel, aluminum, copper and various non-ferrous metal parts. It is inseparable from the spot welding machine electrode in spot welding. Chromium zirconium copper is the most commonly used electrode material in welding. It has the characteristics of anti-oxidation, wear resistance, corrosion resistance, long service life, and high frequency of spot welding.

If the life of the electrode tip is regarded as a cycle, it can be divided into three periods: the initial welding period, the stable period and the final period. The initial welding period refers to the multiple solder joints at the beginning of welding, often with spatter, copper color and a little adhesion. The stable period It is the stage where the welding quality is stable. There is no spatter, copper color and adhesion. At the end of the welding life, spatter, copper color and adhesion will occur again. The welding parameters are different and the proportions of each stage are obviously different. The welding parameters must be expanded appropriately. The proportion of stable period is applicable to construction machinery, metal cabinets, auto parts, hardware welding, electrical switches, metal packaging, chemical containers and other industries.
