U+RSW - A Break-Through Process for Dissimilar Metal Joining in Automotive Industries
TS-036907 — A welding technique that joins two dissimilar metals.
Resistance spot welding (RSW) is critical to automobile manufacturing, with 3,000 to 5,000 spot welds per vehicle. As consumers seek vehicles with better fuel economy, automobile manufacturers have replaced parts built from heavy metals, such as advanced high-strength steel (AHSS), with lighter al…

Method and Device to Monitor & Control Efficiency of the Friction Welding Process
TS-015293 — A device that can be readily attached to inertia or direct drive friction welding equipment to determine energy efficiency in-situ during welding, providing real-time feedback for improving control.
Friction welding is a category of solid-state welding processes that uses frictional heat generation at the weld interface to plasticize the work pieces and produce a metallurgical bond. The welding parameters used in large-scale industrial production are typically determined via trial and error. …

High Velocity Tube Expansion for Making Axisymmetric Joints
TS-014774 — Making axisymmetric joints using pressure created by gas evolution from electrically vaporizing thin wires.
Current state-of-the-art technology for joining by tube expansion is hydroforming or electromagnetic forming (EMF). Hydroforming requires large presses, and EMF is limited to larger diameter products and electrically conductive driving materials. Generally, application of EMF is limited at high en…

Collision Welding Induced by Metal Vaporization
TS-014749 — A new method which uses electrically vaporizing conductors to achieve collision welding safely, efficiently, and in a factory environment.
Traditional explosive welding (EXW) and magnetic pulse welding (MPW) are techniques used to weld dissimilar materials together, which cannot be achieved through traditional fusion welding processes. The result of these methods are known as collision welds, which are observed when a piece of metal …
