A finite element based model incorporating an enhanced friction model to consider the effect of tool tilt angle on the material flow and heat generation during Friction Stir Welding is developed. The friction model is modified by introducing an in plane rotating angle of the friction shear stress between the tool and the workpieces. It is concluded that the tilting induces higher temperature, softer material and greater frictional force in the trailing side of the tool; the material flow in the rear side of the tool with the title angle is considerably enhanced, which assists to prevent the defect generation.
