Abstract
Friction Stir Welding (FSW) has demonstrated a significant potential for joining low melting point non-ferrous metals in several joint configurations. During FSW metals are joined in the solid state due to the heat generated by the friction and flow of metal by the stirring action of a pinned tool. In this investigation, the effect of friction stir welding process parameters like Tool Travel speed, Rotational speed ,and shoulder diameter on ultimate tensile strength and micro structural properties of Friction sir welding joint of 6111-T4 by using Taguchi method. By Factorial and Taguchi design and analysis for process parameters and experimental results gives the maximum responses such as Tensile strength at rotational speed 1100 rpm, tool travel21mm/min, shoulder diameter 26mm. An ANOVA analysis indicates an influence of individual parameters on Ultimate Tensile strength a of welding joint. a mathematical relations are proposed for Tensile strength.
