The study of optimization of process parameters of cold metal transfer (CMT) welding which serves the purpose of joining dissimilar metals using analysis of variance (ANOVA).The response variables of CMT welding have been examined for welding Aluminum 6061 with Mild Steel. CMT is advanced version of Metal Inert Gas Welding (MIG) welding. It welding depends on short circuiting process including low heat input rate and spatter free welding. Heat affected zone in this process is very less as compared to that of other. For increasing the weld quality, the selected process parameters are root gap, current, groove angle and the combined effect of these process parameters on response variables (tensile strength, micro-hardness, and heat affected zone) is observed with the help of ANOVA.
