Investigating Steel Tool Life in the RFSSW Process

Journal of Manufacturing Processes, 2020
Abstract Refill Friction Stir Spot Welding (RFSSW) has demonstrated capability in joining thin sheets of aluminum with dissimilar thickness, alloy, and composition. The process remains to be implemented on a wide scale in the automotive and aerospace industries, partially due to the relatively short number of welds producible by a toolset, prior to ...

The Effect of RFSSW Parameters on Load Capacity of EN AW-6082-T6 Aluminum Alloy and AlCu Bimetallic Joints

International Journal of Advanced Manufacturing Technology, 2023
Abstract This paper presents research into the creation of refill friction stir spot welding (RFSSW) single-lap joints of 6082-T6 aluminum alloy and roll-bonded AlCu bimetallic sheet. The latter sheet comprises aluminum EN AW-1050A and electrolytic copper M1E in Z6 temper condition (after rolling) and with a 1:1 ...

The Analysis of Reasons for Defects Formation in Aluminum Joints Created Using RFSSW Technology

Manufacturing Letters, 2019
Abstract The paper describes and classifies defects in aluminum joints made using refill friction stir spot welding (RFSSW) technology, which has potential for replacing riveting as a default joining technology in aviation. Three defect groups were distinguished: at the sleeve-plunger interface, between the sheets and in the joint axis.

Strength Evaluation of Beam Made of the Aluminum 6061-T6 and Titanium Grade 5 Alloys Sheets Joined by RFSSW and RSW

Composite Structures, 2017
Abstract The paper presents the strength evaluation of the beam made of the sheets from the aluminum alloy 6061-T6 and titanium alloy grade 5. The beam was made of two C-profiles connected by the webs, with the flanges reinforced by the flat bars. Channels were made by bending alloy aluminum 6061-T6 sheets with a thickness of 0.8 mm.

Effect of Rotational Speed on Microstructure and Mechanical Properties of 2060 Aluminum Alloy RFSSW Joint

Metals and Materials International, 2019
Refill friction stir spot welding (RFSSW) is used to weld 3.2-mm-thick 2060 aluminum alloy sheets. In this study, we investigated the formation, microstructures and mechanical properties of the RFSSW joint. The results show that increasing the rotational speed is beneficial to eliminating annular groove but increasing the flash.
