The TIG (Tungsten Inert Gas) method is based on the production of an electric arc by means of an infusible tungsten electrode in an inert gas shield. TIG welding at a glance:
When a tungsten electrode (infusible) is brought closer to the welded material (bonded material), an electric arc appears which melts the material and the TIG binder (metal rod) supplied next to the holder to form a liquid welding pool. After the arc has moved away, the welding pool solidifies to form a permanent joint. The shielding gas is supplied continuously through the welding gun and its gas nozzle which protects the melted metal against the impact of the atmosphere.
The tungsten electrode is supplied with voltage by means of a welding gun coming from a power source (TIG welding machine).
TIG welding machines are mainly used to weld stainless and other high-alloyed steels and materials such as aluminium, copper, titanium, nickel and their alloys.
