Abstract: Friction Stir Welding (FSW), a solid state welding process, look like a most promising techniques for joining an aluminium alloys avoiding a large number of difficulties arising from the use of traditional fusion welding processes. In experimentation, the effect of friction stir welding process parameters like Tool Travel speed, Rotational speed ,and shoulder diameter on mechanical properties and micro structural properties of Friction stir welding joint of 6111-T4 studied by using Factorial and Taguchi design and analysis. The Quantitative results gives the maximum responses such as Tensile strength at rotational speed 1000 rpm, tool travel 18 mm/min, shoulder diameter 24 mm and Hardness at 1100rpm, 18 mm/min and 24mm. 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 and Hardness of weld joint. Whereas a qualitative observations gives are the best for optimal conditions suggested in by prediction model.
