The effect of welding parameters on the mechanical properties of friction stir‐welded dissimilar aluminium alloys in overlap joint configuration was studied. Both the welding configuration and the materials chosen were a typical skin‐stringer configuration, widely used for aeronautical fuselage panels. Mechanical properties were evaluated by means of both hoop stress and T‐pull test. Results show that there is a great dependence of the hoop stress resistance from welding parameters; conversely, T‐pull tests do not show the same dependence. The present work demonstrates the suitability of the x in lap configuration for joining dissimilar aluminium alloys. Copyright © 2013 John Wiley & Sons, Ltd.
