Most modern passenger and commercial diesel vehicle engines are equipped with a turbocharger providing better fuel economy, performance and reduced emissions across the whole world.
Typically a cast Inconel wheel is joined to a carbon steel shaft by Electron Beam Welding producing a deep penetration, narrow fusion zone (HAZ) and near parent metal strength. Welding is performed inside a vacuum environment to ensure high quality.
Parts are either machined to make the joint self-locating or precision tooling is used for clamping to guarantee excellent geometry and minimal post-weld machining. Using finished or semi-finished parts reduces the investment cost of the manufacturing cell for EB compared to other manufacturing processes.
