Abstract—Plasma arc welding is used for high quality joints in the air -crafts, aero space, chemical and petroleum industries. The present work discusses about the weld quality characteristics of mild steel which are commonly used in almost all non specialist steel products like car domestic goods, constructional steel, street furniture signs. In this research welding is carried out at variable values of input parameters (current, gas flow) and same thickness of 3 mm for all work pieces. Current, gas flow are considered as welding processes parameters of PAW process, where as microstructure, hardness and tensile properties are considered as weld quality characteristics.

Index Terms—Plasma arc welding, Microstructure, Hardness, Ultimate tensile strength
