Abstract. Emergent manufacturing demands for superior performance but lightweight structures have pinpointed the development of multi-material and hybrid structures specifically in the aerospace and automotive industrial sectors. Friction stir welding (FSW), a solid-state joining technique has been proven very effective to produce joints between materials possessing extremely diverse thermal and mechanical properties. The present research aims to investigate the feasibility of Al-Ti skin-stringer joints with different plate geometries and placements. The effect of different approaches on material flow, grain morphology, intermittent phases, joint resistance, and microhardness are discussed in depth.
