| Abstract Scope |
Solid state welding leverages the work of plasticity for joining of traditionally unweldable, dissimilar, or otherwise thermally sensitive alloys and microstructures. Energy efficiency and reduced heat inputs compared to fusion welding are advantageous across various solid-state welding techniques, but can vary by several orders of magnitude. This work develops an energy, time- and length-scale framework to analyze the power utilization and efficiency of friction, friction stir, ultrasonic, and collision welding. Weld thermo-mechanically affected zone (TMAZ) sizes and associated effects on weld performance are also considered. |
