An Experimental Study On Mechanical And Microstructural Properties Of Dissimilar Aluminium Alloy Friction Stir Welds

Friction stir welding (FSW), a solid state joining technique is widely used for joining Aluminum alloys in marine, aerospace, automotive and many other applications of commercial importance. In thepresent study, dissimilar Aluminum alloy (AA 6262-T6 and AA 7075-T6) plates were FS welded by varying the weld parameters such as Tool rotational speed, weld speed and axial force with cylindrical tool pin profile. The mechanical properties (hardness and tensile strength) of the Dissimilar Friction Stir welded (DFSW) specimens were tested and compared with the base materials. The observations have been elaborated in detail along with microstructures of parent and welded specimens through Optical Microscopy and it is observed that the weld parameters have a significant effect on mechanical and micro structural properties of the welds.
