    • Abstract
  • A new technique of cross-friction stir spot welding (cross-FSSW) was proposed for improving the mechanical properties of the spot weld joints. This technology was realized by the tool made the short cross-reciprocating movement. Using this technique,experiments were conducted in 4 mm thick sheets of aluminum alloy 5A02 in H14 condition. The results show that the bonding widths of cross-FSSW joints had been increased, the adverse effects of interface distortion and the lack of material of the keyhole had been avoided. cross-FSSW joints were found to be superior to traditional Friction stir spot welds produced under optimum conditions in lap-shear.
