A study of properties of FSW lap joints performed with aluminum alloys used in aerostructure manufacturing (2XXX and 7XXX series alloys) are presented in this work. The effects of different tool designs and welding parameters in the microstructural and mechanical properties of the joints were investigated. The microstructural features were analyzed by metallographic examination while the mechanical properties were studied by microhardness measurements. Typical features of FSW lap joints have been identified such as hook features, cold lap defects or joint uplifting. The extension of HAZ regions and mechanical property reduction was evaluated depending on the welding parameters used to perform the FSW joints. The tool design as well as welding conditions that minimize defects such as effective sheet thinning, hardness drops or wide HAZ regions were established.
