—Tungsten Inert Gas (TIG) welding with filler wire addition is a candidateprocess for welding of UNSS31603/316L austenitic stainless steel. In GTAW, the qualityof the weld is characterized by the weld-bead geometry as itinfluences the mechanicalproperties and its performance during service. This work focuses on the developmentofregression model and optimization using Genetic Algorithm for determining the optimum/near-optimum TIGprocessparameters for obtaining the optimum weld-bead geometry during welding of 316Lstainless steel. Parameters selectedfor study were Welding current, Shielding Gas Flow, Filler Rod Diameter and the response selected was Aspect Ratio.Using the experimental data generated on the influence of process variableson weld -bead geometry, regression modelscorrelating the weld-bead shape parameterswith the process parameters has been developed using Regression Method .ANOVA Analysis was done to obtain the significant parameters. Percent contribution of various parameter found wasShielding gas flow 43.52%, Filler rod diameter 31.09%, Welding current 22.13%. Experimental validation of the modelwas also performed. The optimum result obtained from Genetic algorithm was welding current 80A, Shielding gas8l/min, Filler rod diameter 1.6mm and Aspect ratio of 2.228.
