... of an electrode. The electrode will be either a consumable wire or rod or a nonconsumable carbon or tungsten rod that carries the welding current. The electrode is manually or mechanically moved along the joint, or it remains stationary while the workpiece is moved. When a nonconsumable electrode is used, filler...

It is most commonly used to weld two overlapping sheets or plates that may have different thicknesses. A pair of electrodes conducts electrical current to the joint. Resistance to the current flow heats...
