Development and characterization of dissimilar joint between AA2024-T3 and AA6061-T6 by modified friction stir clinching process

Friction stir spot welding (FSSW) is one of the effective solid-state welding strategies to achieve good joint efficiency between dissimilar aluminum alloys. However, the formation of tool-induced keyhole (a stress raiser) is inevitable during the FSSW process. This study explores the possibility of eliminating keyhole with the aim of improving the properties of the joint by Modified Friction Stir Clinching (MFSC) process. The tensile-shear and...
