Friction Stir Welding, the solid-state technique has gained vantage in recent decades for welding dissimilar non-ferrous metals efficiently. Specifically, friction-welded Aluminium and Magnesium alloy joints are much desired in automotive and aerospace applications for their good specific strength. The dependency on additional filler materials or fasteners in conventional techniques deems them inapplicable and is also associated with solidification defects. The controlled heat generation and dissipation throughout the FSW process are often attributed to the resulting high joint strengths; which inquires the investigation of heat transfer during the operation. The present work deals with the analytical and numerical modelling of heat input for friction stir welding of AA 6061 and Mg AZ31B alloys and a comparison of the predicted results. The numerically simulated results are in good agreement with the developed analytical models and offer a good insight for predicting the characteristics of the FSW joints. [ABSTRACT FROM AUTHOR]
