TIG welding is an arc work procedure using a tungsten infused electrode. The arc is primed between the electrode and the piece to weld. A protective gas passes through the nozzle to protect the welding bath and the tungsten electrode. Currently, this procedure is used to weld stainless steel, inconel, monel, copper and its alloys. The advantages of TIG welding are the high quality of the joints and the lack of slags and spray. TIG welding has a stable arc that enables good control of the fusing bath, however TIG welding is a process suited to all types of metal using a rod as a hard facing metal. TIG welding (Gas Tungsten Arc Welding) is referred to using the abbreviation GTAW.
