Sacrificial Layer to Facilitate Welding of Thin Foils
TS-065430 — Cost-effective method to prevent damaged electrodes when welding thin foils.
Manufacturing of automotive lithium-ion batteries and battery packs is attracting growing attention with the driving demands of electric vehicles. During battery assembly, multi-layers of metal films, functioning as anodes, cathodes, or bus-bars are welded together. Achieving satisfying weld quali…

Self-filling Friction Stir Welding Processing
TS-065427 — The Ohio State University has developed a novel self-filling friction stir welding tool that eliminates keyhole defects caused by tool pin retraction.
Friction stir welding (FSW) and friction stir processing (FSP) are solid-state processes that utilize the heat generated from a rotating pin tool to soften the base metals for fusion and repair, respectively. However, keyhole defects are inevitably left after retracting the tool pin, which can ge…

Ultrasonically assisted wire additive manufacturing process and apparatus
TS-054013 — The ultrasonically assisted wire additive manufacturing process and apparatus is a new innovation that uses power ultrasound (UA) for benefits in processing molten metals. The UA energy is directly applied in the local deposition pool, which makes this new hybrid process applicable for building parts with any size and geometry.
Additive manufacturing (AM) is the process of 3D printing for industrial use. Instead of countertop devices printing small toys from plastic, industrial AM is used on a much larger scale to create engine blocks, plane components, and many other products made of metal alloys. AM is traditionally do…
