Question

what is electrode in welding??

Answer 1

Welding electrode 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:

maintaining uniform current density, concentrating current at welding points, and maintaining thermal balance during welding.

Answer 2

Welding electrodes. In arc welding, anelectrode is used to conduct current through a workpiece to fuse two pieces together. Depending upon the process, the electrode is either consumable, in the case of gas metal arc welding or shielded metal arcwelding, or non-consumable, such as in gas tungsten arc welding.
