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. 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.
FLUX CORED ARC WELDING (FCAW)
This is an electric arc welding process which fuses together the
parts to be welded by heating them with wan arc between a
continuous flux filled electrode wire and the work. Shielding is
obtained through decomposition of the flux within the tubular
wire. Additional shielding may or may not be obtained from an
externally supplied gas or gas mixture. The process is normally
applied semi automatically; however the process may be
applied automatically or by machine. It is commonly used to
weld large diameter electrodes in the flat and horizontal position
and small electrode diameters in all positions. The process is
used to a lesser degree for welding stainless steel and for
overlay work.
