These inert gases are stable during welding, wherein it does not diffuse particles to the weld bead. MIG welding uses inert shielding gases (argon, helium, nitrogen, or a mixture of the three). Both of these processes are performed using the same welding machine. They’re often seen as one welding technique because apart from the shielding gas, the welding process is exactly the same. Difference Between MIG and MAG Weldingīoth metal inert gas (MIG) and metal active gas (MAG) are fusion welding processes and belong to the GMAW family. Metal active gas welding (MAG) has become another option alongside MIG, as it creates an avenue for different weld results and materials such as carbon steel. MIG uses a consumable wire electrode which is fused with the base metals in the weld pool, whereas TIG uses a non-consumable tungsten electrode and the use of filler metal is optional and is added to the weld pool separately.Īs the wire welding process has diversified and improved over time, different shielding gases have been taken into consideration for various types of metals and welding procedures. Simultaneously, the shielding gas travels along the welding gun to keep the weld free from atmospheric contamination.Īlthough MIG and TIG welding are quite similar in several aspects, they have some key differences. As the electric arc melts the electrode wire it is then fused along with the base metals in the weld pool. Filler metal is constantly fed through the welding gun. In this welding process, the base materials are joined together through a welding current. Metal inert gas (MIG) welding is a subtype of gas metal arc welding (GMAW).
