mig welding
Gas-shielded metal fusion
MIG welding is a process that joins metals by feeding a continuous wire electrode through a handheld gun while shielding the weld with inert gas—usually argon or a carbon dioxide mixture.
The acronym stands for metal inert gas.
MIG welding is popular for its speed and ease of learning compared to other welding methods: I learned MIG welding in a weekend workshop.
