Two main problems exist with friction stir spot welded joints; remaining of a keyhole after welding and low strength of joints. In this paper, a novel method is proposed to address both problems in a simple and cost-effective way. This process is nam

In the present paper, a novel solid-state welding method is introduced and investigated which can be used as a repair method for thick aluminum plates. The process is named “multilayer friction stir plug welding”. This process was proposed to ove
