Refill friction stir spot welding (RFSSW) has several advantages compared with other mainstream single-point joining or mechanical fastening processes. Although many organisations recognise these advantages and benefits, further research is required in order to implement this technology into large-scale production and increase the current technology readiness level. This report describes the collection of baseline mechanical properties and microstructure characterisation of RFSSW welds on various transport aluminium alloys used in the transport sector, intending to promote industrial uptake.
