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