Abstract
A welding process known as Plasma Arc Welding (PAW) has been performed on AISI 304 austenitic and AISI 430 ferritic stainless steel combination in this paper. A wide range of industries including chemicals, pharmaceuticals, textiles, food, drink, pulp and paper are using ferritic-austenitic stainless steel. The major part of this study contributes to parameter optimization, microstructural behavior and mechanical properties. Defect free welds are obtained at certain welding parameters only. In this experimental study, the macro and micro structure of base metal zone, weld zone and heat affected zone was predicted by using optical microscopy and Scanning Electron Microscopy (SEM). The microscopy tests revealed uniform distribution of sub-grains over the weld zone. Furthermore, mechanical tests such as tensile test and hardness test showed enhanced strength and hardness on the welded zone.
