Numerical Analysis of Thermal Friction Stir Weld-ing (FSW) Application in Aerospace Industry

Abstract

In this work, Friction Stir Welding (FSW) of 2017A-T451 aluminum alloy for a constant tool rotational speed 1250 rpm is investigated and analyzed. 3D numerical simulation has been carried out with the aid of ANSY code. In this context, two steps are performed; a mesh system is adapted to the geometry (plaque and tool) in order to use the finite elements. Secondly; the predicted result of plate temperature has been compared to experimental result. The surface temperature of the plate increases with the passage of the rotating tool; this is due to the increasing of friction between the tool and plate. This increase is slow until 300 s then it decreases rapidly. A good agreement is noted between the experimental and predicted results. According to this result, ANSYS provides a satisfactory prediction for the FSW.
