Parametric Optimization of TIG Welding on Stainless Steel 316

The main objective of this paper to find out near optimal solution for welding parameters in TIG (tungsten inert gas) welding. The mechanicals properties like Tensile strength, Impact force, Hardness of the welded joints are influenced by many welding process parameters. The weld quality is affected by weld bead shape during joining operation.In present work, an attempt is made to model the welding process for predicting the bead shape parameters (commonly called as bead geometry parameters)of welded joints. This paper also includes the modeling and optimization of bead shape parameters for tungsten inert gas (TIG) welding process and further bead shape strength is predicted in the last part of the paper. Taguchi and ANOVA technique is used to find the optimal solution.
