Stress analysis of welded ellipsoidal end-to-shell joint of a stainless steel tank

Welding is most widely used in metal joining. In Tungsten Inert Gas (TIG), defining the process and appropriate values for process is essential in order to control heat-affected zone (HAZ) and get the required effect of residual stress. In this investigation, metallurgical study was carried out on t...
