This is an arc welding process where hardfacing wire is fed continually from a spool through the welding torch into the arc, where it is melted and transferred to the work piece.
In the case of MIG welding, also known as Gas Metal Arc Welding (GMAW) the weld pool is protected from the atmosphere with a stream of shielding gas. These MIG processes are very flexible, i.e. they can be partially or fully mechanized and they are suitable for a wide range of applications.
Wire is also used as the hardfacing consumable in the Submerged Arc Welding (SAW) process. In this process a mineral based fluxing powder flows around the consumable wire and is melted by the arc. It forms a gaseous shield around the arc and also forms a slag on top of the weld pool, thereby shielding the cooling weld pool from the atmosphere.
Benefits of MIG are:
Can Be Partially Or Fully Mechanized
Suitable For Wide Range Of Applications
