Formation Mechanisms for Entry and Exit Defects in Bobbin Friction Stir Welding
: Bobbin friction stir welding (BFSW) is an innovative variant for the solid state welding process whereby a rotating symmetrical tool causes a fully penetrated bond. Despite the process development, there are still ...
Internal Material Flow Layers in AA6082-T6 Butt-Joints during Bobbin Friction Stir Welding
(MDPI AG, 2019)
Bobbin friction stir welding with a double-sided tool configuration produces a symmetrical solid-state joint. However, control of the process parameters to achieve defect-free welds is difficult. The internal flow features ...
