Editing Electrode (section)

== Welding electrodes ==
In [[arc welding]], an electrode 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 arc welding]], or non-consumable, such as in [[gas tungsten arc welding]]. For a direct current system, the weld rod or stick may be a cathode for a filling type weld or an anode for other welding processes. For an alternating current arc welder, the welding electrode would not be considered an anode or cathode.
