Aluminum alloy is a very useful material in light manufacturing. Friction stir welding (FSW) is a solid state assembly process that is achievable for this material. This work aims to characterize the quality of the weld joint by an operation of shaping (folding), it aims to study the rate of elastic return in this weld joint after a folding operation. In this context, the elastic return for the folding process has been modeled using experimental tests under optimal welding conditions.

The friction stir welding process is an innovative technique for joining metals using plasticity, without presenting the fusion. It was first applied to aluminum alloys, for example copper, steel alloys, polymers and others. In this work the effects of the rotational speed, the speed of travel and the axial force of the tool were grouped in a mathematical model to quantify their influences on the weld seam. In this context and with of the experimental tests, the desired objective through this study is to describe the tensile strength of the cord resulting from this welding operation, for the qualification of this type of parts with an optimum adapted to a given application.
