Detailed explanation of medium frequency spot welding machine electrodes


Intermediate frequency spot welding machine electrodes generally use chromium zirconium copper, or beryllium bronze, or beryllium cobalt copper. Some users also use red copper for welding, but only in small batches.

Since the electrodes of spot welders are prone to heat and wear after working for a long time, resulting in increased contact internal resistance and reduced current, so appropriate electrode materials should be selected. Different electrodes are used to weld different materials. For example, when welding copper, tungsten electrodes must be used.

Chrome-pick copper electrodes can be used with pure tungsten rod electrodes embedded in the middle. Generally, dispersion-strengthened copper alloy (Al2O3-Cu) is used directly, and its service life is 5-10 times that of chromium-pick copper. The toughness of pure tungsten is relatively poor. If it cannot be made in China, it is usually treated with liquid nitrogen.

It avoids the phenomenon of electrode sticking, the welding part does not turn yellow, the solder joints are beautiful, excellent electrical conductivity and thermal conductivity, good high temperature performance, and the alumina copper electrode can play a greater role when combined with the electrode grinding function of the medium frequency spot welder.
