Spot Friction Welding of Ultra High-Strength Automotive Sheet Steel
<p>Spot friction welding (SFW) was performed on ultra high strength steel (UHSS) steel sheet commonly used in automobile manufacturing. Alloys studied included DP780, DP780EG, DP980, and DF140T sheet steel of varying thickness from 1.2 mm to 1.4 mm. Welding was accomplished using a PCBN standard …

Numerical simulation of friction welding processes: An arbitrary Lagrangian-Eulerian approach
… solver with thermomechanical friction contact for numerical simulation of friction welding processes are described. A finite strain associative coupled thermoplasticity model is used, which is suited for the large deformations characteristic of friction welding processes, and …

3 dimensional flow and thermal modelling of the friction stir welding process
Friction Stir V/elding (FSW) is a relatively new welding process, having being patented in 1991 by The Welding Institute, Cambridge. This process has great advantages in welding difficult to weld aluminium alloys. The process gives low post weld distortion, can weld thick sections in a single pass …

Development and Characterization of Friction Bit Joining: A New Solid State Spot Joining Technology Applied to Dissimilar Al/Steel Joints
<p>Friction bit joining (FBJ) is a new solid-state spot joining technology developed in cooperation between Brigham Young University of Provo Utah, and MegaStir Technologies of West Bountiful Utah. Although capable of joining several different material combinations, this research focuses on the …

Modelling of friction stir spot welding
Friction stir spot welding (FSSW) is a solid-state welding process which is especially useful for joining precipitation-hardened aluminium alloys that undergo adverse property changes during fusion welding. It also has potential as an effective method for solid-state joining of dissimilar alloys. …
