Question

Difference between metal inert gas welding and tungsten inert gas welding

Answer 1

Gas metal arc welding (GMAW), sometimes referred to by its subtypesmetal inert gas (MIG) welding or metalactive gas (MAG) welding, is a weldingprocess in which an electric arc forms between a consumable wire electrode and the workpiece metal(s), which heats the workpiece metal(s), causing them to melt and join.
TIG (tungsten inert gas) welding, also known as gas tungsten arc welding (GTAW), is an arc welding process that uses a non-consumable tungsten electrode to produce the weld. ... The weld area is generally protected from atmospheric contamination by use of an inert shielding or cover gas (argon or helium)
