Formability and mechanical property of refill friction stir spot–welded joints

Welding in the World, 2021
The effects of rotation speed and plunge depth on macro/microstructures and mechanical properties of dissimilar 2195/2219 aluminum alloy joints produced by refill friction stir spot welding (RFSSW) were investigated. The results show that some shallow annular grooves present on the joint surfaces depending on the process parameters.

Refill Friction Stir Spot Welding Dissimilar Al/Mg Alloys

Journal of Materials Engineering and Performance, 2019
Dissimilar Al/Mg alloys were joined by refill friction stir spot welding (RFSSW) in this work. The effect of sleeve plunge depth on microstructure and mechanical properties of the joints was studied. The results showed that sound joint can be obtained at sleeve plunge depth of 2.4 mm.

Refill friction stir spot welding of 5083-O aluminum alloy

Journal of Materials Science & Technology, 2018
Abstract 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.

Improvement of refill friction stir spot welds by auxiliary material addition

Materials Science and Technology, 2020
An 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 ...

Friction Stir Spot Welding of AA2024-T3 with Modified Refill Technique

Key Engineering Materials, 2020
The 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 ...

Recent Advances In Keyhole Defects Repairs Via Refilling Friction Stir Spot Welding

Materials Today: Proceedings, 2019
Abstract The goal of any welding processing is to produce a defect-free sample that will serve the intended purposes. The major setback in friction stir spot welding (FSSW) is the keyhole that always left at the centre of the spot after welding process and also the keyhole that left at the end of friction stir welding and processing (FSW/P).
