What is the difference between MIG and MAG welding?

Question

Accepted Answer

MIG welding uses a solid wire electrode and a shielding gas, while MAG welding uses a flux-cored wire electrode with a shielding gas.

MIG welding stands for Metal Inert Gas welding, while MAG welding stands for Metal Active Gas welding.
MIG welding uses a solid wire electrode that requires a separate shielding gas to protect the weld pool, while MAG welding uses a flux-cored wire electrode that produces its own shielding gas when heated.
MIG welding is typically used for non-ferrous metals like aluminum, while MAG welding is more suitable for ferrous metals like steel.
MIG welding produces cleaner welds with less spatter, while MAG welding is better for outdoor or windy conditions due to the self-shielding nature of the flux-cored wire.
