Characteristics of manual welding process on carbon steel repair welding using buttering bead

Methods of repair welding are different to production welding for welding position, welding process, welding power source, heating methods. This study investigated proper the welding process used the welding process SMAW and GTAW in the weldment of inconel filler metals. Mechanical test showed that SMAW and GTAW process had higher mechanical properties than those of material specification. Both SMAW and GTAW welding process can appy the repair welding. In comparison, GTAW welding process had more higher mechanical properties in the weldment.
