For single response process parameter optimization, Taguchi analysis is used. By varying the settings, the user may obtain variable results that always depend on selected data parameters. Hence optimization of multi responses and their characteristics is the solution. Mechanical properties and their improvements are critical for Cold Metal Transfer Welding. In this paper, a multi-response objective optimization process, the DEAR approach is proposed for Stainless steel welding using the CMT process. Various process parameters for this type of welding are, Nozzle to tip distance is varied to test the multiple responses like Tensile test, Surface Roughness. Taguchi L8 Orthogonal Array was picked up to acquit the experiment. Various parameters were optimized for the butt- welded specimens by decided approach and each process parameter, and its percentage contribution in the outcome was identified.
