Refill Friction Stir Spot Welding of 2198-T8 Aluminum Alloy
Transactions of the Indian Institute of Metals, 2017Refill friction stir spot welding (RFSSW) technology was used to weld 2 mm-thick 2198-T8 aluminum alloy in this work. As one of the most significant factors affecting the joint mechanical properties, effect of the tool rotating speeds on microstructure and mechanical properties of the RFSSW joint was mainly discussed.

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.

Refilling of Pinhole in Friction Stir Spot Welding Using Waste Chips
2019Friction stir welding (FSW) is considered as a sustainable and green alternative to conventional welding techniques. However, the pinhole left after welding is one of the major defects. This study discusses a novel technique of refilling the pinhole, left after conventional friction stir spot welding (FSSW) of aluminium alloy AA6082 overlapping sheets,

Parametric study of two-stage refilled friction stir spot welding
Journal of Manufacturing Processes, 2016Abstract Two-stage refilled friction stir spot welding (TFSSW) is a novel refilling process, based on conventional FSSW. This process is done in two steps and with two independent tools, conventional and refilling tool. In this paper, TFSSW is studied, using Al 1100 sheets which were 2 mm in thickness, to evaluate effect of welding parameters on ...

Reducing Cycle Times of Refill Friction Stir Spot Welding in Automotive Aluminum Alloys
SAE Technical Paper Series, 2020<div class="section abstract"><div class="htmlview paragraph">A major barrier, preventing RFSSW from use by manufacturers, is the long cycle time that has been historically associated with making a weld. In order for RFSSW to become a readily implementable welding solution, cycle times must be reduced to an acceptable level, similar to that
