Why is usage of the term GWW preferable to MIG for gas metal arc welding?

To determine

Reason of using the term GMAW over MIG for gas metal arc welding.

Answer

GMAW is preferred over MIG for gas metal arc welding as other gases apart from argon are used in metal arc welding.

Explanation

The term MIG stands for Metal inert gas welding, an inert gas is used to protect the weld from impurity. Initially, Argon as an inert gas was used forshielding.

Later, after developments in the technology associated with welding, carbon dioxide CO2 and oxygen O2 are also used for shielding.

Argon was used for shielding the weld. It was termed as MIG welding and was named as Gas Metal Arc Welding (GMAW) by American Welding society because other gases can also be used for shielding.
