Gas Tungsten Arc Welding. An arc welding process that uses an arc between a non-consumable tungsten electrode and the weld pool (base metal of strip). A high quality full fusion weld is achieved using no filler metal. The GTAW process is also commonly referred to as Tungsten Inert Gas (TIG) welding.
Gas Tungsten Arc Welding. See "TIG Weld."
Gas Tungsten Arc Welding. A gas shielded welding method where the heating is produced using a non-consumable tungsten electrode to transfer the arc to the work piece.
Gas Tungsten Arc Welding. An arc-welding process wherein coalescence is produced by heating with an arc between a single tungsten (nonconsumable) electrode and the work; shielding is obtained from a gas or gas mixture; pressure may or may not be used and filler metal may or may not be used; also called TIG welding.
