Metal Inert Gas (MIG) welding is a gas metal arc welding (GMAW) process that uses a continuous solid wire electrode which is heated and fed into the weld pool from a welding gun.
MIG is an attractive alternative to MMA, offering high deposition rates and high productivity
When it comes to MIG welding, it uses a combination of heat and an electrode wire to create a molten pool to fuse two pieces of metal together.
In MIG welding, you can easily join a variety of metals, and the type of wire used is determined by the type of metal being welded.
