MIG WIRES
Gas metal arc welding (GMAW), sometimes referred to by its subtypes metal
inert gas (MIG) welding or metal active gas (MAG) welding, is a
semi-automatic or automatic arc welding process in which a continuous and
consumable wire electrode and a shielding gas are fed through a welding gun.
A constant voltage, direct current power source is most commonly used with
GMAW, but constant current systems, as well as alternating current, can be
used. There are four primary methods of metal transfer in GMAW, called
globular, short-circuiting, spray, and pulsed-spray, each of which has
distinct properties and corresponding advantages and limitations.
