MIG Welding Benefits All position capability
Higher deposition rates than SMAW
Long welds can be made without starts and stops
Minimal post weld cleaning is required
MIG Welding Shielding Gas
The shielding gas, forms the arc plasma, stabilizes the arc on the metal being welded, shields the arc and molten weld pool, and allows
smooth transfer of metal from the weld wire to the molten weld pool.
There are three primary metal transfer modes:
Spray transfer
Globular transfer
Short circuiting transfer
