Purpose: Taguchi design has been adopted in order to identify optimal parametric combination for desired quality of weld. Microscopy was conducted to study the effect of welding input process parameters (welding current, gas flow rate and nozzle to plate distance) on MIG weld microstructures of AISI 409 ferritic stainless steel and AISI 316L austenitic stainless steel. Design/methodology/approach: A plan of experiments based on Taguchi technique has been used. Findings: The present work is planned to investigate some perspectives of GMAW dissimilar joints between AISI 409, a ferritic stainless steel and AISI 316L a austenitic stainless steel. Research limitations/implications: The main objective of the present study was to apply the Taguchi method to establish the optimal set of control parameters for the welding. The Taguchi method is employed to determine the optimal combination of design parameters, including: current, gas flow rate and nozzle to plate distance. the observed data have been interpreted, discussed and analyzed by considering yield strength , ultimate tensile strength and percentage of elongation combined with use of principal component analyses (pca) method. Practical implications: Dissimilar welding is the joining between two different materials by any welding process. Dissimilar weld has made considerable attention in many fields, such as in ship industries and nuclear power plant. Originality/value: The result computed is in form of contribution from each parameter, through which optimal parameters are identified for maximum tensile strength and percentage elongation. This paper presents new results of optimization using principal component analyses.
