Abstract

For the effective applications of the welded materials they do not melt or recast. So there is an emerging process which improvises the product quality which is nothing Friction Stir Welding process. During the FSW process, the non consumable tool rotates to plunge and travels along the weld line to produce a high quality of joint. FSW process eliminates the fusion welding problems such as crack, porosity and solidification shrinkage. The aim of the present work is to evaluate the microstructure and mechanical properties of friction stir welded AA6061 cast and wrought aluminium alloy joint. In FSW, the process parameters such as welding speed of 50 mm/min, rotational speed of 800 rpm and axial force of 8 kN was used to make the joint. Two samples were welded by keeping one sample of wrought alloy as an advancing side and cast alloy in retreating side and another sample of weld is produced by keeping the plate alternatively on both sides. The welded samples were characterized by using metallurgical microscopy and universal tensile testing machine. The changes in microstructures, micro hardness and tensile properties were discussed.
