The tensile properties(Table 2)and joint defect(Fig.3)dependence on the welding speed can be explained by the following two factors.The first factor is associated with the metal flow.During the FSW process,the tool rotation opposes the traversing weld direction in the retreating side of the weld.Due to the frictional forces between the tool shoulder and the substrate,the surface material is displaced in both the rotational direction and the welding direction.
