Effect of Friction Stir Welding Process Parameters on Tensile strength of Dissimilar Welded Joint

Nilesh V. Desai, Dr. K. H. Inamdar

Abstract: In the present work, the effect friction stir welding (FSW) process parameters on the mechanical properties of dissimilar friction stir butt welded aluminium (Al) alloy, AA6061-T6 and stainless steel, 304L were investigated. FSW tools having fixed shoulder diameter, pin tip diameter and pin length with tapered cylindrical (TC) pin profile was used for experimental work. The FSW parameters used were, tool rotational speed (rpm), welding speed (mm/min), plunge depth (mm) and tool offset (mm). The ultimate tensile strength (UTS) of the joint is considered as the main criterion of the joint performance. Taguchi method of optimization was used to determine optimum level of parameter and Analysis of Variance (ANOVA) is done in order to determine significance of each parameter. The results showed that the rotational speed has more contribution among all other parameter followed by welding speed.
