Abstract : In this research the influence of friction stir welding tool pin profiles on the mechanical properties and
microstructure of ZE-41 Mg alloy joint have been investigated. Two tool pin geometries i.e. straight cylindrical and threaded
cylindrical with 18 mm diameter of shoulder, and 6 mm pin diameter made from high carbon steel (HCS) were used to
prepare the weldments. The joints were welded using friction stir welding process at various tool rotational and traverse
speeds. Tensile properties of the joints were evaluated. Metallurgical properties were investigated and correlated with
mechanical properties of the joints. It has been found that threaded cylindrical pin geometry produced weld joints having
maximum ultimate tensile strength compared with straight cylindrical pin. Fine grained microstructure was achieved with
threaded cylindrical pin geometry.
