Tig and Mig Welding

The 2 main welding is TIG and MIG welding. TIG stands for Tungsten inert gas, what it isan arc welding process that uses a nonconsumable tungsten electrode to produce the weld. The weld area is protected from atmospheric contamination by a shielding gas (usually an inert gas such as argon), and a filler metal is normally used, though some welds, known as autogenous welds, do not require it.
