Abstract
This study compared friction stir welding undertaken parameters such as tool rotation speed, transverse speed, and tool shoulder diameter on weld joint and compared ultimate tensile strength weld joint by underwater friction stir welding and normal friction stir welding using vertical machining center. For statistical analysis, the Taguchi L9 method was adopted. Ultimate tensile strength is tested as a response which shows that the ultimate tensile strength achieved by the underwater friction stir welding was higher than the normal friction stir welding. Regression analysis and analysis of variance were used as a statistical analysis method. From the analysis, it was observed that high tool rotation speed with minimum tool transverse speed gives maximum tensile strength for underwater friction stir welding and that of normal friction stir welding.
