Why do medium frequency spot welding machine electrodes deform?

When welding the medium frequency spot welder, one of the most important accessories is the electrode, which directly affects the quality of the welding joints. A common wear and tear is electrode deformation. Why is it deformed?

When welding workpieces, the service life of the electrode gradually decreases as the number of solder joints increases, because the electrode has to withstand a huge welding current during operation, and at the same time, the working surface of the electrode directly contacts the surface of the high-temperature solder joint.

Normally deformed electrodes have fine metal flanges on their heads, while severe deformation is caused by insufficient high-temperature hardness of the electrode material or poor cooling. So what are the requirements for the strength of electrode materials of medium frequency inverter spot welding machines?

1. It has high oxidation resistance at normal temperature and high temperature, and has sufficient hardness and high temperature resistance strength.

2. It has suitable electrical and thermal conductivity at normal temperature and high temperature, effectively preventing the taper deformation of the electrode hole and maintaining accuracy and long life.
