Evaluation Study on Angular Distortion and Residual Stress of Stainless Steel Pulsed TIG Weldment

Abstract:

Article Preview

The aim of this study was to investigate the effect of pulsed current welding parameters on angular distortion and residual stress of TIG weldment. Autogenous TIG welding was applied on type 316L stainless steel sheet to produce bead-on-plate welds. Angular distortion was determined using the mean vertical displacement method. Residual stress was determined using the hole-drilling strain- gage method. The results showed that the pulsed current TIG welding has a number of advantages, including lower heat input and consequently a reduction in distortion and residual stress of weldment.
