ABSTRACT
The Metal Arc Gas-Shielded (MAGS) Welding can be used on a wide range of metals, positions and thicknesses. If the material has a high thermal conductivity a shielding gas which increases the heat transferred to the work piece should be used. Welding wires are usually supplied on 12-18 kg reels layer wound in such a way as to ensure that the wire releases smoothly during the welding operation. The electrode wire is fed from the reel to the tube via the wire feed rollers. Dip transfer takes place at 15-25 volts and 40-200 amps on wire diameters up to 1.2 mm. Although the angles are the same as manual metal arc (MMA) welding the stance of the operator may change with the MAGS process. Flux-cored arc welding (FCAW) is a variation of the MAGS process. One characteristic of the self-shielded process is the use of long electrode extensions. The welding process is widely used in a variety of industrial situations.
