Abstract :This study consisted of the effects of vertical tool load on failure value in FSSW of CuZn30. Tensile-shear test, microstructural examination, microhardness, vertical tool load, and temperature measurements were utilized to reveal the influence of FSSW process. According to the results, the tool load plays a key role on the features of joint. Not only low tool load, but also excessive load used leads to drop in the tensile-shear values. The spot weld region was characterized by stir and heat-affected zones and these have various microhardness values ranging from 108.2 HV to 150.2 HV. The temperature measurements show that the peak temperature increased with increasing tool load value..
Keywords : FSSW, brass alloy, vertical tool load, tensile shear failure load
