Effect of Welding Parameters on Mechanical Properties of Plasma Transferred Arc Welded SS 202 Plates

Abstract:

Plasma arc welding is an arc welding process wherein coalescence is produced by the heat obtained from a constricted arc setup between a tungsten electrode and the workpiece material. In the present work, the 6 mm thick stainless steel 202 plates are welded using plasma transferred arc welding. The welding parameters such as powder feed rate, welding voltage and welding current were carefully selected. The effect of these parameters on mechanical properties such as tensile strength, impact strength and hardness of the joints were studied. As a result, the increase in tensile strength and impact strength was obtained for the high current, low voltage and powder feed rate. But the highest hardness was attained for the joints made at low current, low feed rate and low voltage.
