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

Abstract

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.
