Abstract

Friction stir welding (FSW) was employed to join 10 mm thick AA2024-T6 aluminium alloy plates to overcome the fusion welding related problems such as grain coarsening in fusion zone, heat affected zone (HAZ) softening, lower joint efficiency and premature joint failure. The center cracked test (CCT)...
