Abstract

The utility of P-GMAW process has been discussed in reference to regulation of pulse arc in the form of short arc, chop arc and double-pulsed welding process. The unique potential features of P-GMAW process has been described in exploration of new welding procedures as extra narrow gap and deep-gap welding used in relatively thick plate and thick wall pipe welding. The use of most favourable control of weld isotherm and weld thermal cycle of P-GMAW in development of innovative products of extra thick and thin section welding is explained. The products developed improved quality which is otherwise difficult to produce by any other welding process.
