Abstract

Welding of various grades of stainless steel is still a potential area of research. In our investigation is carried out through welding of butt joints of austenitic to ferritic stainless steels using gas metal arc welding. Parametric studies have been done by planning the experiments making the butt joints as per plan, conducting visual of the welded specimens, tensile testing, hardness measurements at different zones and microstructural studies. The input parameters taken into consideration are current, gas flow rate and nozzle to plate distance. Response parameters in the context of optimization have been ultimate tensile strength, yield strength and percentage elongation. Thickness of the material welded is 5 mm, 50 mm width, 60 mm length of each piece, Inert gas used is Ar+5%CO2. Grey-Taguchi method has been applied for process optimization. Optimized conditions for study have been evaluated. The results of optimization have been validated by confirmatory tests. The work is, principally, directed to the study of weld quality under varied welding parameters through experiments and optimization.
