Tentative Analysis of Welding Deformation of Austenitic Stainless Steel 316 in TIG Welding

Tungsten inert gas (TIG) welding is broadly useful in manufacturing process. The present work carried on the optimization of weld process parameters with Taguchi approach for the deformation 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 key parameters. ANOVA was perfumed to obtain significant parameter which gives the percentage contribution of each process parameter under operating condition
