MIG-MAG welding is a semi-automatic welding process carried out using the energy released by an electric arc in a gas atmosphere. The acronyms MIG and MAG stand for “Metal Inert Gas” and Metal Active Gas respectively. The difference between the two processes is the composition of the gas.
MIG-MAG welding lends itself well to full automation with robotic installations because it uses a neutral gas that does not react with the molten metal, unlike the MAG process. It allows for incredible flexibility in implementation.
