Characterization of Friction Stir Weld Joint for Aluminum Alloy (AA6061) coated with Mg Particles
Friction stir welding (FSW) is a solid-state welding process which is having broad scope of joining materials which are relatively hard to be welded by fusion welding process. FSW process is highly energy-efficient and eco friendly as compared to the fusion welding. The purpose of this experimental work is to investigate and analyze the mechanical properties like Tensile Strength, Hardness and Impact strength by using Universal Testing Machine, Rockwell Hardness Tester and Charpy Impact Test Machine respectively on butt joint. Friction stir welding operation is performed on Aluminium alloy 6061 coated with magnesium particles. The optimum values were optimized by developing a Taguchi optimization technique. The experimental results have been analyzed by using ANOVA statistical technique to know the effect of process parameters. During this experimental work it is observed that AA 6061 has higher values of Tensile Strength and Hardness due to its strain hardening effect.
