TIG welding

TIG welding (Tungsten Inert Gas) involves generating an electric arc using a non-consumable tungsten electrode in an inert gas shield (carbon dioxide (CO2), argon (Ar), helium (He) or their mixtures). During TIG welding, current is supplied through a tungsten electrode, which is resistant to high temperatures and does not melt. A welding arc comes out of this electrode, which heats up and melts the welded element. There is a shielding gas nozzle around the electrode.
