چکیده
Abstract In this study, similar aluminum alloys AA5052 with additional carbon fiber-reinforced polymer composite (CFRP) interlayer were selected to investigate the effect of welding parameters (rotational speed and dwell time) on mechanical properties, joint efficiency, microstructure friction stir spot weld joint. The maximum tensile shear load was 1779.6 N efficiency 14.6% obtained at rotational 2,000 rpm 2 s time, which is 39.5% higher than value low 850 time. Meanwhile, microhardness 58 HV attained in keyhole region time 5 s, 22.4% compared speed. SEM-EDS results reveal presence intermetallic compounds (Al–Mg–C), enhance bonding between elements.
