Abstract

In this study, orbital friction stir lap welding of 360 mm diameter AA5083-H321 tube to 350 mm diameter AA5083-O flange was investigated. The influence of rotational and travel speed of tool with triangular frustum pin on the metallurgical structure and mechanical properties of orbital friction stir lap welded samples were studied. The results indicated that defect free orbital lap joints are successfully obtained using tool rotational speed of 650 and 800 rev min −1 with a constant travel speed of 40 mm min −1 . The strengthening mechanism in the stir zone is solid solution strengthening and dislocation looping. The maximum joint strength was achieved at a welding speed of 650 rev min −1 and 40 mm min −1 . Failure of tensile shear test samples occurred far from the friction stir welding zone.
