MIG/MAG Welding
Gas Metal Arc Welding (GMAW) is one of the most versatile and widely used welding processes. Whether using inert gas (MIG) or active gas (MAG), this technique delivers high productivity and excellent weld quality for diverse applications from automotive to heavy fabrication.
How MIG/MAG Welding Works
MIG (Metal Inert Gas) and MAG (Metal Active Gas) welding use a continuously fed consumable wire electrode and shielding gas to create strong, clean welds. The main difference is the type of shielding gas used.
An electric arc forms between the wire electrode and the workpiece, melting both to create the weld pool. The shielding gas protects the molten metal from atmospheric contamination, resulting in high-quality welds.
MIG vs MAG:
MIG (Inert Gas)
Uses pure argon or argon/helium mix. Ideal for aluminum, stainless steel, and non-ferrous metals.
MAG (Active Gas)
Uses CO2 or argon/CO2 mix. Preferred for carbon and low-alloy steels.
The Welding Process
Wire Feed
Continuous wire feeds through the torch
Arc Initiation
Contact with workpiece creates arc
Gas Shielding
Shielding gas protects the weld pool
Metal Transfer
Wire melts and transfers to weld
Solidification
Weld pool cools and solidifies
