USE OF FRICTION STIR WELDING ON PRIMARY STRUCTURES OF AIRCRAFTS INSTEAD OF RIVETED JUNCTION
D. Desgaches, AIRBUS, France
Typical junction area of fuselage is riveted for common commercial aircraft. These junctions are sized by fatigue and damage tolerance criterion, due to pressurization loading, with single-shear or double-shear geometries, and potential overlap.rnThe use of Friction Stir Welding could be a solution to solve criticality of fuselage junctions due to the proof of its high mechanical properties.
