FLUXCORED ARC WELDING(FCAW): This is an electric arc welding process which fuses together the parts to be welded by heating them with an
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.
Position of MIG Torch
The angle of MIG torch to the weld has an effect on the width of the weld.
The welding gun should be held at an angle to the weld joint. Hold the gun so that the welding seam is viewed at all times. Always wear a welding
helmet with the correct shade lenses and proper safety equipment.
The electrode wire is not energized until the gun trigger is pressed. The wire may therefore be placed on the seam or joint prior to lowering your
helmet.
