Influence of Tool Pin Profile and Welding Parameters on Tensile Strength of Aluminium Alloy 5052 during FSW


The friction stir welding (FSW) is a solid state welding process. It uses non-consumable tool for joining plates with advantages such as low distortion, no shielding gas required and fine recrystallized microstructure. FSW parameters such as tool rotation, welding speed, tool geometry, axial force and tool plunge depth play an important role during welding. In the present work, FSW between the 6mm thick AA5052 aluminium alloy plates was investigated with the combination of two different tool pin profile (Taper Pin-Left Hand Threaded (LHT) and Square Pin) at welding speeds of 30mm/min and 40mm/min with tool rotation speed 850rpm and 1250 rpm. Tensile testing was carried out and comparative study was done to know the best parameter from the selected ones. Maximum tensile strength 378.12 N/mm2 was obtained with taper pin-LHT at welding speed 40mm/min with tool rotation 1250rpm.
