N2 - The requirement for a probe, or pin, in friction stir spot welding (FSSW) leads to an undesirable keyhole and ‘‘hooking,’’ which can influence the fracture path and weld strength. Furthermore, the full weld cycle for FSSW is typically longer than ideal for the automotive industry, being 2 to 5 seconds. Here, it is shown that using a novel pinless tool design it is possible to achieve high lap shear strength (~3.4 kN) in thin aluminum sheet (~1 mm thick), with short weld cycle times (
