Electron beam welding has become a vital technology in many industries. Several specific applications of the technology are highlighted to illustrate how varied, useful, and in some cases, critical EB Welding has become.
The typical Electron Beam Welding machine for aerospace applications has a large work chamber with a high voltage (150 kV) electron gun of substantial power (up to 30 kW). The work chamber is furnished with high precision work piece manipulators under computer and CNC control for the quality and precision demanded within the aerospace industry sectors.
Most modern passenger car and commercial vehicle engines are equipped with turbochargers. Manufacturers of these units had conventionally used inertia friction welding techniques to join the Inconel wheel to the Carbon steel shaft. Although this joining method produced a joint of adequate strength, the post-weld machining, grinding and heat treatment operations were expensive and time consuming.
