Exploring the boundaries of refill friction stir spot welding: influence of short welding times on joint performance

Welding in the World
Abstract Refill friction stir spot welding is a solid-state spot-welding technique suited to lap joining of thin aluminium sheets, including difficult-to-weld 2xxx series alloys that are prone to hot cracking during fusion welding processes. Long welding time is an ongoing challenge that hinders industrial adoption of the process.
