Abstract
In the last ten years, aerospace and automotive industries have addressed large attention to a new welding technology based on a solid-state process, called friction stir welding (FSW). FSW process shows several advantages, in particular the possibility to weld dissimilar aluminium alloys. In this paper, thin aluminium alloy 2024-T3 and 6082-T6 sheets, 0.8 mm thick, have been welded in the rolling direction by μFSW (FSW for ultra-thin sheets). Both similar and dissimilar joints have been successfully produced and analysed. Mechanical characterization has been executed through static and uniaxial fatigue tests with a constant load amplitude. Finally, microhardness and residual stress measurements have been executed on welded sheets for each joint typology.In the last ten years, aerospace and automotive industries have addressed large attention to a new welding technology based on a solid-state process, called friction stir welding (FSW).
