Automotive Welding

Welding for NASCAR race cars throttle shafts.

The welds performed by Electron Beam Engineering, Inc. are not limited to airplanes, spacecraft and offshore oil rigs. Our work can also be found on land – as automotive welding, inside the engines of high performance racing engines. One of the components that EBE welds for the automotive industry is the throttle shafts for NASCAR race cars. This component goes between the throttle linkage and the carburetor, and in the past it was always Gas Tungsten Arc (TIG) welded by hand. Many years ago, during an actual race, one of the cars suddenly lost power when the throttle shaft broke due to a fractured TIG weld. When the manufacturer approached EBE for help, it was a simple solution: redesign the weld joint and switch to electron beam welding. Since the switch to electron beam welding, no throttle shafts have broken.
