•Gas Metal Arc Welding: It is an arc
welding process that produces
coalescence of metals by heating them
with an arc between a continuous
consumable filler metal electrode and the
work. Shielding is obtained entirely from
an externally supplied gas or gas mixture.
Some methods of this process are called
MIG or CO2 welding (non proffered terms).
