MIG (Metal Inert Gas) welding uses various gases which are crucial in the welding process. The main gases employed are a blend of carbon dioxide with argon or simply each one independently. Argon, an inert gas, creates a protective envelope around the weld pool, therefore preventing oxidation and contamination from foreign substances. Consequently, welds produced have a high surface finish and good mechanical properties. Carbon dioxide comes under the category of reactive gases. Alone or together with argon, it can serve to increase the arc voltage and the heat input, which is advantageous for welding thicker materials. Some of the determining factors are the type of gas include some aspects as the kind of metal that is welded, the thickness of the material, and the characteristics of the weld. Foe instance, to weld aluminum, a higher percentage of argon is used, whilst steel is welded using a mixture with more carbon dioxide.
