GTAW, or TIG welding, is a precise welding process that uses a nonconsumable tungsten electrode and inert shielding gas. GTAW can be used on a wide variety of metals, and can be performed manually or ...
The shielding gas flows through the outer jet, serving the same purpose as in TIG welding. Figure 4.1: Schematic diagram of plasma -welding. Resistor R limits the current in the pilot arc which can be ...
Gas tungsten arc welding (GTAW, also known as TIG welding) also requires a shielding gas such as an argon/helium mixture or an argon/hydrogen mixture. TIG welding is used on thin metals because it ...
