Basic welding guide
MIG (GMAW/FCAW) Basic Welding Technique
Two different welding processes are covered in this section (GMAW and FCAW), with the intention providing
the very basic concepts in using the MIG mode of welding, where a welding gun is hand held, and the electrode
(welding wire) is fed into a weld puddle, and the arc is shielded by an inert welding grade shielding gas or inert
welding grade shielding gas mixture.
GAS METAL ARC WELDING (GMAW)
This process, also known as MIG welding, CO2 welding, Micro Wire Welding, short arc welding, dip transfer
welding, wire welding etc., is an electric arc welding process which fuses together the parts to be welded by
heating them with an arc between a solid continuous, consumable electrode and the work-piece. Shielding is
obtained from an externally supplied welding grade shielding gas or welding grade shielding gas mixture. The
process is normally applied semi automatically; however the and fairly thick steels, and some non-ferrous
metals in all positions.
