Investigation of Dissimilar Joint between 356 and 7075 of Semi-Solid (SSM) Aluminum Alloy by Friction Stir Welding

Abstract:

The objective of this research was to investigate the effect of parameters on the microstructure and mechanical properties of friction stir welded butt joints of dissimilar aluminum alloy sheets between Semi-Solid Metal (SSM) 356 and 7075. The base metal of SSM 356 and 7075 was located on the advancing side and the retreating side, respectively. The cylindrical pin was used as the welding tool geometry. Friction stir welded using different tool rotation speed (710, 1000 and 1400 rpm) and welding speed (80, 112 and 160 mm/min). The result indicated that the maximum average tensile strength of 205.13 MPa was achieved for the joint produced at tool rotation speed 1000 rpm, welding speed 160 mm/min. In addition, the metallurgy and welding structures of combined two types aluminium showed more definite than the base metal.
