Abstract: The present work focuses on studying the effect of pin profile and tilt angle of the tool on the mechanical and microstructural characteristics of FSWed Cu-Zn30 brass joints. Three different pin profiles viz. Conical, threaded cylindrical and cylindrical were used to fabricate the joints at five different tilt angles viz. 0°, 1°, 2°, 3° and 4°. Fifteen joints were produced by different combinations of input parameters. The fabricated joints were tested for tensile, hardness and microstructural properties in order to explore the weld quality. The results of a current study clearly show that tool tilt angle and pin profile significantly affects the weld quality. Threaded pin profiled tool is observed to produce better quality joint at 3° tool tilt angle as compared to conical and cylindrical pin profiled tools. The results of mechanical testing were also correlated with the microstructural changes occur during the welding process.
