Joining 1.1‐ and 2.1‐mm Al Sheets by Friction Stir Spot Welding

Material Design &Processing Communication, Volume 2025, Issue 1, 2025.
This study used friction stir spot welding (FSSW) to weld 1.1‐ and 2.1‐mm AA6061‐T6 sheets at 560, 710, 900, and 1120 rpm at a fixed dwell duration of 5 s. It was determined how much heat was supplied into the FSSW, and the cycle temperature that occurred throughout the FSSW technique was carefully documented.

Joining Optimization, Temperature, and IMC Evaluation for AL to Steel Friction Stir Spot Welding

Material Design &Processing Communication, Volume 2025, Issue 1, 2025.
Friction stir spot welding (FSSW) effectively solves many problematic welding metals, such as dissimilar metals and thin alloy sheets. Carbon steel‐AISI 1006 top sheet and an aluminum alloy AA2024‐T3 bottom sheet were joined by FSSW with a cylindrical pinless tool. Joints are evaluated in terms of temperature, mechanical characteristics, microstructure,

Shear strength optimization for FSSW AA6060-T5 joints by Taguchi and full factorial design

Journal of Materials Research and Technology, 2020
Statistical tools have shown to be very useful in the optimization of processes such as welding. Optimization is understood as the determination of the welding combinations that will lead to the maximization of a desired property, such as strength.

Improved Lap Shear Strength of Ti6Al4V/CF‐PPS Joints Through Electrical Discharge Machining Surface Texturing

Material Design &Processing Communication, Volume 2025, Issue 1, 2025.
This study investigates friction‐assisted spot joining (FASJ) of Ti6Al4V alloy and carbon fiber–reinforced polyphenylene sulfide (CF‐PPS) composites using electrical discharge machining (EDM) surface pretreatment combined with process parameter optimization. EDM texturing generated superficial roughness that promoted mechanical interlocking between the

Relationship between weld rip diameter and fatigue fracture mode for friction stir spot welded tension‐peel joints

Fatigue &Fracture of Engineering Materials &Structures, Volume 47, Issue 6, Page 2127-2138, June 2024.
Abstract In this study, the effects of variations in the weld rip diameter on fatigue properties were investigated based on the fatigue fracture mechanism using tensile peeling‐type friction stir spot welding (FSSW) joints. The results of the fatigue test showed that the high and low applied force ranges exhibited base metal fracture and weld area ...
