MIG and TIG Welding

GMAW, commonly known as MIG welding, is an arc welding process which produces the coalescence of metals by heating them with an arc between a continuously fed filler metal electrode and the work.

The TIG process derives the heat for welding from an electric arc established between a non-consumable tungsten electrode and the part to be welded. Filler metal, if used, is manually feed into the weld puddle when TIG welding.
