ABSTRACT Industries are focusing on various cost reduction initiatives by choosing alternative material without compromising quality. The main aim of this paper is to identify such an alternate material for Duplex Stainless Steel/Duplex Stainless Steel (DSS/DSS) similar metal weld joint. Similar and various dissimilar metal weld joints like DSS/DSS, DSS/Corten-A, DSS/Cold Rolled Steel and DSS/Hot Rolled Steel were assessed in this paper and the results have been compared to find out the superior dissimilar metal in terms of Tensile strength. Objective of this work is to optimize the process parameters for the best superior dissimilar metal weld joint by using Taguchi method. Voltage, Current and filler feed rate were chosen as a control factors considering the impact on the input variables. Ultimate tensile strength has been taken as response variable to calculate the signal-to-noise ratio. Analysis of variance (Anova) was used in order to identify the percentage contribution for all the factors as well as high significant factor which is contributing for the optimum resul
