Refill friction stir spot welding of 5083-O aluminum alloy
Journal of Materials Science and Technology, 2018Abstract In this work, refill friction stir spot welding (RFSSW) was used to weld 2 mm-thick 5083-O alloy. The Box–Behnken experimental design was used to investigate the effect of welding parameters on the joint lap shear property. Results showed that a surface indentation of 0.3 mm effectively eliminated the welding defects.

Friction Stir Spot Welding of AA2024-T3 with Modified Refill Technique
Key Engineering Materials, 2020The quality of welded joints of FSSW is mainly dependent on the processing parameters while the main disadvantage of this process is the creation of an exit hole. Process parameters, namely tool dimensions, tool rotational speed, and stir time were changed and their impact on bond dimensions and weld strength was investigated using 2024-T3 Al Alloy ...

Refill friction stir spot welding of aerospace alloys in the presence of interfacial sealant
Welding in the World, 2021Refill friction stir spot welding (refill FSSW) is one of the most industrially promising friction stir spot welding variants. The absence of an exit hole improves the effectiveness of surface treatments and minimizes damage by fouling. Aerospace aluminium alloys AA2024-T3 and AA7075-T6 with a thickness of 2 mm were used in this investigation.

Improvement of refill friction stir spot welds by auxiliary material addition
Materials Science and Technology, 2020An innovative technology to improve the bonding of refill friction stir spot welding by auxiliary material addition was proposed. The annular groove was eliminated and the energy absorption was increased. Weld bonding was enhanced because the improved technology affected the hook, retractable line and stir zone (SZ) shape significantly: (1) the ...
