About TIG Welding
What is TIG (Tungsten Inert Gas), GTAW (Gas Tungsten Arc Welding) or HeliArc Welding
TIG welding is a precision arc welding process that uses a non-consumable tungsten electrode and a shielding gas, generally argon. In some cases mixed gases are used such as argon and helium or argon and nitrogen. This process can be used for fusion welding or with filler metal. In most applications the filler metal is added manually using a 36" (91.4cm) cut-length TIG welding rod.
Cold wire feed machines are available to improve TIG welding quality and productivity by using a spool of wire which reduces variables and Increases TIG welding productivity by eliminating time-consuming arc stops-and-starts common with cut-length-rod.
TIG welding is clean and quiet and produces beautiful cosmetic appearing welds which are found in many applications.
