Aluminium alloys series 2XXX and 7XXX are not usually considered weldable by traditional methods. They are mostly used as a part of aerospace structures. The common practice joining technology is riveting. Growing technology of friction stir welding (FSW) has shown promising results in welding of these alloys. In this paper we have investigated application of FSW technology in aircraft structures mainly as substitution of riveting on stringer reinforced panels. Manufacturing process steps were

Knowledge platform for setting basic welding parameters has been created and comparison of a sample of riveting and FSW technologies on a simple final element method model sample was examined in order to identify differences in stress distribution character in the riveted and FS welded samples.
