Introduction of electrode life of resistance spot welding machine!

Resistance welding equipment is a resistance welding equipment that forms a nugget based on resistance heat. It has a wide range of applications in the welding of carbon steel, stainless steel, aluminum, copper and various non-ferrous metal parts. In spot welding, the electrodes of spot welding machines are inseparable. 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 head is taken as a cycle, it can be divided into three periods: the initial welding period, the stable period and the final period. It is the stage of stable welding quality, and there is no spatter, copper color and sticking. The final stage is the welding life, and spatter, copper color and sticking occur again. The welding parameters are different, and the proportions of each stage are obviously different. Appropriate welding parameter expansion is required. The proportion of the stable period is suitable for industries such as construction machinery, metal cabinets, auto parts, hardware welding, electrical switches, metal packaging, and chemical containers.
