焊接电极

焊接电极 are installed in the weld head to touch and maintain contact with the workpieces through the full weld schedule. The welding electrodes play three different roles in resistance welding:

保持一致的电流密度,将电流集中在焊点上,并在焊接过程中保持热平衡。

Electrodes are available in many shapes. Electrode material and shape are determined by considering the force necessary for welding and the thermal conductivity of the workpieces.

In conventional macro-welding, e.g. car body assembly, the electrodes are made of copper alloys and usually water-cooled. However, in micro-welding, the electrodes are made of a wide variety of conductive and refractory materials depending on the parts to be joined, and are air-cooled.
