Weld metal workpieces together by tungsten intert gas (TIG) welding. This arc welding process welds metal workpieces using the heat generated between an arc of electricity struck between a non-consumable tungsten metal electrode. Use an argon or helium inert gas to shield the weld from athmospheric contamination.
