Abstract:
Friction stir welding of AA2014 aluminium alloy was performed at 931 rpm and 41 mm/min speed. Weld joint properties were compared with the base metal. Optical microstructure and FESEM analysis with energy dispersive spectroscopy (EDS) were performed. Microhardness and tensile tests were performed to study the mechanical behavior of base metal and FSW joint. Direct current based corrosion test was carried out to study the corrosion behavior. Mechanical performance of AA2014 was reduced after the welding. Corrosion resistance of the weld joint was higher than the base metal. Presence of precipitates affected the performance of base metal and weld joint.
