Scope of arc-welding, have increased in the various engineering field like aerospace, nuclear, and underwater industries where complex geometry and hazardous environments necessitate fully automated systems. Even traditional applications of arc welding such as off-highway and automotive manufacturing have increased their demand in quality, cost, accuracy, and volume to stay competitive. As a result, process parameters are needed to improve the existing process of welding. Metal inert gas (MIG) welding process has successfully used for joining similar and dissimilar metals. In this study dissimilar metals, stainless steel (SS-304) and low carbon steel plates are joined by MIG welding successfully. Three parameters of MIG welding viz. current, voltage and travel speed are taken for the analysis. A plan of experiments based on Taguchi technique has been used to acquire the data. The analysis for signal-to-noise ratio was done using MINITAB-13 software for higher-the-better quality characteristics. The significance of each parameter was studied by using the ANOVA (Analysis of variance). Finally the confirmation tests were performed to compare the predicted values with the experimental values which confirm its effectiveness in the analysis of tensile strength of the joint.
