Effect of Friction Stir Welding Speeds on Interface Formation of Dissimilar T-joint Aluminum Alloys

Abstract

The aim of this work is to investigate the impact of friction stir welding parameters on the interface formation of dissimilar metal T-joint between AA7075 and AA5083. The experimental works demonstrated that the interface morphology was significantly sensitive to welding speed. Increasing welding speed was useful for effective skin thickness and effective bonding width. However, this would lead to defect formation. The tensile strength of the joints was measured for both the skin and stringer tests.
