Article Preview

In this paper a bonding-FSSW hybrid method is proposed and the joining procedure as well as the microstructure and performance of bonding-FSSW hybrid joints of AZ31 aluminum alloy is examined . The results show that the bonding agent has little influence on the forming and mechanical property of FSSW nugget, the shear-resisting property of the hybrid joints with sealing glue is equivalent to FSSW joints, in bonding-FSSW hybrid joint with high-strength bonding agent, the shear-resisting property of joints are apparently superior to that of pure FSSW or bonding joints. Tiny and uniform equiaxial grains are formed in the WN(Welding nugget zone) and coarse grains are formed in TMAZ (Thermomechanically affected zone) and HAZ (Heat affected zone), but with unequal size. The good properties of the hybrid joints are obtained by choosing the optimal joining parameter.
