Tungsten-Inert Gas (TIG) Welding

Tungsten-Inert Gas (TIG) Welding Points : Tungsten-Inert Gas (TIG) Welding In TIG welding the weld zone in shielded form the atmosphere by an inert gas that is ducted directly to the weld, zone where it surrounds the tungsten electrode. The two inert gases that are used most often are argon and helium The TIG process offers many advantages. TIG welds are stronger, more ductile and more corrosion-resistant than welds made with ordinary shielded- metal-arc welding. In addition, because no granular is required, it is possible to use a wider variety of joint designs than in conventional shielded-arc welding or stick-electrode welding. The weld bead has no corrosion because flux temperature cannot occur, and because of the gas fluxing there is little or no post weld cleaning operation. There is also little weld metal splatter or weld sparks that damage the surface of the base metal as in traditional shielded-arc welding.
