What is GMAW?

Submitted by: Administrator

Gas Metal Arc Welding is a welding method more commonly referred to as GMAW or MIG welding.

Typically used in the automotive and sheet metal industries, GMAW can be an automatic or semi-automatic process. GMAW provides high quality welds at a low cost to the manufacturer.

This arc welding application feeds a GMAW metal consumable electrode and shielding gas through the welding gun. An electrical current travels down the electrode and strikes the arc between the metal being welded and the wire electrode.

The advantages of GMAW include:

Speed - GMAW is a fast welding application

User-friendly - This welding approach is easy to set up and implement.

Cheap - GMAW equipment tends to be more affordable and more available than other welding equipment.

GMAW is used on these materials:
Steel, Aluminum, Copper, Nickel, Magnesium and other non-ferrous materials.
