ABSTRACT- Tungsten Inert Gas (TIG) welding is a widely applied manufacturing process. The present work carried on the optimization of weld process parameters with Taguchi approach for the distortion control applied to Austenitic stainless steel 316 structures of 8.5 mm thickness with two pass TIG weld process. Taguchi is applied for the optimization of weld parameters control. In this study the distortion of TIG, welding process was evaluated using weld current, Weld Angle and the weld speed as the main parameters. A L9 orthogonal array was selected for the design of experiments towards the distortion optimization caused by butt welding. ANOVA was perfumed to obtain significant parameter which gives the percentage contribution of each process parameter under operating Condition.

Keywords- Key word: GTAW, austenitic stainless steel, distortion, Taguchi method, ANOVA analysis, parameter optimization
