Metal Inert Gas or MIG weld process have in common the electrode used as the filler wire which is continuously fed and heating the job with an arc is established on the work, total or partial inert gas used for shielding the produced arc. There is no flux used for weld, helium, argon, carbon-
There are two types of MIG welds are used, one fully automated and other is semi-
This welding process is said for semi-
MIG welding has large used in automobile industry, aircraft parts welding, pressure vessel manufacturing and many other places.For welding tool steels, carbon, silicon and low allow steels, stainless steel, aluminium and its alloy, magnesium, nickel and its alloy, copper and its alloy, titanium and so many metals.
It is used for refrigerator parts manufacturing .
There are many advantages of MIG welding mention bellow:
Joints can produce with deep penetration.
The metals thickness can not be vary with this MIG welding process. Thick and thin metals are welded very effectively.
This welding process is very suitable for large scale production unit because, it can be performed much faster than other types of welding process like TIG etc.
Large amount of metal can be deposited on the work piece.
MIG welding process can reduces the welding cost, because it produces neat and clean metal deposit on the work piece. Spatter free and smooth welding surface is produced, so it is no need to extra cleaning.
