Inert gases are use for welding is because in the welding process, the heat will actually hasten up the process of oxidation(rusting) happening on metals.
Oxidation process(rusting) requires oxygen, thus, by using inert gas, it will purge the surrounding of oxygen preventing the oxidation process from happening.
MIG welding equipped with co2 is named as MAG(Metal active gas process).It is used bcz of its lower cost nd fulfills the requirements of non precise welds generally.Co2 gas is employed for metals having lower boiling points.Today's trend to use this gas is practice for trainers nd students.

used in what?
Tungsten Inert Gas (orTIG) welding is also referred to as GTAW (Gas Tungsten Arc Welding) and by the term Heliarc® which was the Linde Company's trade name for the TIG process when it was originally introduced.The welding arc is started with a sharply pointed tungsten electrode shielded by inert gas. A separate filler rod is fed manually into the weld puddle in much the same way as is done when gas welding.The process is well suited for aluminum.
mig welding is Metal Inert Gas welding. it typically uses Constant voltage DC+ current. It uses a wire feeder that supplies the electrode to the weld puddle and shields the molten weld puddle with inert gas (argon/co2 blend). Filler wire and shielding gas depend on the metal being welded.
inert gas
metal active gas, doing gas metal arc welding with a gas that isn't inert
composition of the gas: 131 (Inert), 135 (Active)
metal inert gas (MIG) welding
MIG stands for metal inert gas. It is a non-standard term for gas metal arc welding (GMAW) and flux cored arc welding (FCAW) according to the American Welding Society (AWS). It is simply Metal Inert Gas.
metal inert gas (MIG) welding
As an inert gas, it shields the weld from oxygen and corrosion during the melting process. Tig welding means "through inert gas".

Argon is an inert gas. At the high temperatures which are reached during welding the metals involved can get highly reactive. An inert environment prevents chemical reactions.
