Concave and Convex Electrode

The resistance welding electrodes are widely used in automobile electrical equipment industry.

The electrodes produced by brazed contain cavities. Since these cavities are not always figured out, the contact resistance of electrodes manufactured in this way varies, and their cooling performance is not constant, resulting in a shorter service life. We use BACK-CAST technology and able to achieve a fully connection between the electrode insert and electrode shank. This results in extremely low electrical contact resistance between insert and shank, producing exceptionally good electrical conductivity, and in turn high thermal conductivity, which ensures highly efficient cooling of the electrode tip.

Our back-cast technology composite electrodes are an innovative solution in resistance welding technology. They combine the advantages of non-ferrous metals and copper, stable hardness at high temperatures, high electrical resistance and high thermal conductivity.
