Quality improvement of bobbin tool friction stir welds in Mg-Zn-Zr alloy by adjusting tool geometry

The bobbin tool friction stir welding (BTFSW) technique was applied to a Mg-Zn-Zr alloy, ZK60-T5. The effects of shoulder diameter and stir pin geometry on the macrostructure, microstructure and mechanical properties of the BTFSW joints were studied. Weld quality was sensitive to the interaction of...
