A pinless embedded tool used in FSSW and FSW of aluminum alloy
Journal of Materials Processing Technology, 2013Abstract A pinless tool design was proposed to achieve high butt tensile strength in aluminum alloy sheets (∼3 mm thick) in friction stir welding (FSW), where a 7 mm long cylindrical insert rod made of aluminum alloy was tightly embedded into a hollow cylindrical tool.

Friction Stir Spot Welding (FSSW) - A Literature Review
SAE Technical Paper Series, 2007<div class="htmlview paragraph">The Friction Stir Spot Welding (FSSW) process is a derivative of the friction stir welding (FSW) process, without lateral movement of the tool during the welding process. It has been used in the production of aluminum doors, engine hoods, and decklids in the Japanese automotive industry.

Friction Stir Spot Welding (FSSW) of Aluminum Sheets: Experimental and Simulative Analysis
Key Engineering Materials, 2013Friction Stir welding (FSW) is a solid state joining process developed by TWI (The Welding Institute) in 1991. This technology is suitable for joining different materials even considered difficult to be welded using more traditional techniques and it is appropriate to weld materials in different configurations (such as butt, lap, circumferential, T ...

Pinless tool for FSSW of AA 6061-T6 aluminum alloy
Journal of Materials Processing Technology, 2019Abstract Pinless tools have been proposed to eliminate pinhole problems during friction stir welding; while strength of the joint could be decreased. Two probe tools with pin lengths of 2 and 3 mm and two pinless tools with the scroll groove and L-shaped grooves were used for lap welding of 2 mm thick 6061-T6 aluminum alloy sheets.

Influence of FSSW parameters on fracture mechanisms of 5182 aluminium welds
Journal of Materials Processing Technology, 2010The influence of the tool rotational speed, the probe plunge depth and the shoulder penetration depth on weld microstructure and on the weld strength have been studied. The shear tests showed that the friction stir spot welds fail by nugget pullout. Three microstructural factors play a determinant role on the weld's strength: the size and location of ...

Thermo-Mechanical Modeling of Friction Stir Spot Welding (FSSW)
SAE Technical Paper Series, 2006<div class="htmlview paragraph">This paper presents on-going finite element modeling efforts of friction stir spot welding (FSSW) process using Abaqus/Explicit as a finite element solver. Three-dimensional coupled thermal-stress model was used to calculate thermo-mechanical response of FSSW process.

Parametric study of FSSW of aluminium alloy 5754 using a pinless tool
Welding in the World, 2014A parametric study of friction stir spot welding (FSSW) of lap joints in aluminium alloy 5754 using a pinless tool with scrolled shoulder is presented. Experimental plan was done according to the response surface methodology (RSM), where tool rotation speed varied between 988 and 3511 rev/min, plunge rate between 24.4 and 150 mm/min and dwell time ...

Effect of grain orientation on the corrosion resistance of FSSW joints made in AZ31B
Corrosion Engineering, Science and Technology, 2017ABSTRACTLocalised corrosion at the weld periphery of AZ31B friction stir spot welds has been associated with microstructural evolution during the welding process. Several attempts have been made to correlate these changes to the corrosion resistance of a joint; however, the influence of grain reorientation arising from the welding process has been ...
