It’s an MIG welding process is the heating the job with an electric arc established between a continuously fed metal electrode. In this process, No flux is used but the arc and molten metal are shielded by an inert gas which may be argon, helium and carbon dioxide or a gas mixture.
- The following Base metals commonly welded by MIG welding:
- Carbon,alloy steels
- Stainless steels
- Heat resistance alloy
- Aluminum and its alloy
- Copper and its alloys
- Magnesium and its alloys
This process is used for the welding of carbon, silicon and low alloy steels, stainless steel, aluminum, magnesium, copper, nickel, etc. MIG welding has been used successfully in industries like- Air craft, Auto mobile, Pressure vessel and Ship building etc.
