Enhanced friction model for Friction Stir Welding (FSW) analysis: Simulation and experimental validation [PDF]

International Journal of Mechanical Sciences, 2017
Friction is one of the main heat generation mechanisms in Friction Stir Welding (FSW). This phenomenon occurs between the pin and the workpiece as the rotating tool moves along the weld line. An accurate friction model is essential for obtaining realistic results in a FSW simulation in particular temperature, forces and torque. In this work, a modified

Asymmetry Thermal Analyses of Self-Supporting Friction Stir Welding

Frontiers in Materials, 2022
Due to the inherent issue of requiring rigid back support, friction stir welding (FSW) has serious limitations for the welding of hollow structures. Self-supporting friction stir welding was proposed to join hollow aluminum extrusions, which could reduce
