The consumable filler metal ingas metalarc welding is also the electrode. The molten weld puddle is shielded by an externalshieldinggas.What is GMAW and GTAW?InGas MetalArc Welding (GMAW), a consumable electrode is used. This causes the electrodematerialto melt and deposit on the weld bead. Because a non-consumable electrode is used duringGTAWor TIG welding, noelectrodematerial is deposited on the weld bead.Gastungstenarc welding (GTAW), commonly referred to as tungsten inert gas (TIG) welding, is a type of arc welding that uses an inert tungstenelectrodeto create the weld.
