TIG WELDING IS THE CLEANEST WELDING PROCESS TODAY

GAS TUNGSTEN ARC WELDING

Tig welding is a little more tedious and more time consuming but produces a kick a-- weld. Gas tungten arc welding (GTAW),also know or called TIG (tungsten inert gas),and sometimes refered to as Heliarc, is a process that generates an arc between a non-consumable tungsten electrode and the work- piece. The electrode and the weld are protected by a shielding gas, and filler metal may or may not be used. This type of work differs from the other arc welding processes because the electrode is non-consumable and not used as filler material. GTAW is more like oxyfuel welding in terms of the skills needed to manipulate the torch with one hand and the filler rod with the other. GTAW requires another layer of coordination because most machines usually have a foot activated or foot pedal amperage control. Like gas metal arc welding, gas tungsten arc welding is a clean process because the shielding gas eliminates the need for flux and the resultant slag.
