3 MIG/GMAW –In this process the arc is formed between a continuous, automatically fed, metallic consumable
electrode and welding job in an atmosphere of inert gas, and hence this is called metal inert gas arc welding

When the inert gas replaced by carbon dioxide then it is called CO2 arc welding or metal active gas (MAG) arc
welding.
Application – Ferrous metal welding
