Leak Proof Tubular Welds:Deformation-Resistance Welding Simplifies Tube Joining

A solid-state welding process developed by Anthony Ananthanarayanan, a Delphi technical-welding fellow and his engineering partner Desi Flerbst, recently emerged from the lab and is being commercialized at SpaceForm Inc., a recent Delphi Technology Inc., spin-off. The Michigan-based startup is transitioning the Delphi Deformation Resistance Welding (DRW) process into applications well beyond the fuel-system components originally envisioned by its inventors. In addition to the monotube shocks, other potential automotive applications include under-body, roof frame, and rocker-panel assemblies. Compared to stamped metal, tubular structures made with DRW result in lighter, more fuel-efficient cars that are stronger and safer.

Abstract


A solid-state welding process developed by Anthony Ananthanarayanan, a Delphi technical-welding fellow and his engineering partner Desi Flerbst, recently emerged from the lab and is being commercialized at SpaceForm Inc., a recent Delphi Technology Inc., spin-off. The Michigan-based startup is transitioning the Delphi Deformation Resistance Welding (DRW) process into applications well beyond the fuel-system components originally envisioned by its inventors. In addition to the monotube shocks, other potential automotive applications include under-body, roof frame, and rocker-panel assemblies. Compared to stamped metal, tubular structures made with DRW result in lighter, more fuel-efficient cars that are stronger and safer.
