In the Tungsten Inert Gas Welding (TIG) welding process the arc is formed between a tungsten electrode and the workpiece in an inert atmosphere of argon or helium. The small intense arc provided by the electrode is ideal for high quality and precision welding. When filler metal is required, it must be added separately to the weld pool.
