MIG Welding Process

The MIG welding process was developed to meet the production demands of the war and post war time economies. This welding process utilises an electric arc power source, continuously fed consumable MIG wire shielded by gas.

A number of terms are used for the process such as:

MIG – Metal inert gas welding
MAG – Metal active gas welding
GMAW – Gas metal arc welding

Selecting a good MIG welding equipment will make all the difference when it comes to MIG welding.
The wrong type or poor quality equipment can cause frustration, poor weld quality and waste a lot of time.

Whilst a wide range of MIG welding equipment is available the development of new inverter technologies have made equipment easier to use and set up often by automating many features allowing the welder to concentrate on

welding technique.

The MIG welding process was first patented for the welding of aluminium in 1949 in the USA.
The process uses the heat that is generated by an electric arc formed between a bare consumable wire electrode

and the work piece. This arc is shielded by a gas to prevent oxidation of the weld.

In the MIG process an inert shielding gas is used to protect the electrode and weld pool from contamination and enhance the arc. Originally this gas was helium.

In the early 1950’s the process became popular in the UK for welding aluminium using argon as the shielding gas.

Development in the use of different gases resulted in the MAG process. This is where other gases were used, for example carbon dioxide and sometimes users refer to the process as CO2 welding. Gases such as oxygen and carbon dioxide were added and are active constituents to the inert gas to improve the welding performance.


Although the MAG process is in common use today it is still referred to as MIG welding although technically this is not correct. The process began to prove itself as an alternative to stick electrode (MMA) and TIG (GTAW) offering high productivity and deposition rates. The process also helps reduce any weld defects from the increased stop/starts used in MMA. However, the welder must have a good knowledge of the system set up and maintenance to achieve satisfactory MIG welds.
