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.

RafaMIG 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.

What is the principle of tig welding?
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.
What is the welding for MIG welding?
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.
Why should gas metal arc welding oonly be used in climate controlled areas?
inert gas
How does MAG weld mean?
metal active gas, doing gas metal arc welding with a gas that isn't inert
What is the difference between welding process 131 and 135?
composition of the gas: 131 (Inert), 135 (Active)
