Optimization and non-destructive test analysis of SS316L weldments using GTAW

This work aims at optimization and analysis of SS316L weldments using TIG Welding, SS316L is selected over other grades because of its lower carbon content and its weldability properties. The welding parameters are being assessed by means of Taguchi's L9 orthogonal array with varying gas flow, current and bevel angle with the predictions achieved the sample is welded. The level of importance of welding parameters for tensile strength is determined by using analysis of variance (ANOVA) and it was concluded that gas flow played the prominent role and the bevel angle was least contributor. The op...
