Electron Beam Welders
Since the publication of the first practical electron beam welding equipment by Steigerwald in 1958 the electron beam (EB) welding spread rapidly in all branches of engineering where welding can be applied. To cover the most various requirements, a countless number of EB welder types has been designed, differing in construction, working space volume, work-piece manipulators and beam power. The electron beam generators (electron guns) designed for welding applications can supply beams with power ranging from a few watts up to about one hundred kilowatts. "Micro-welds" of tiny components can be realized, as well as deep welds up to 300 mm (or even more if needed.
The vacuum working chambers of various design may have the volume of only a few liters, but vacuum chambers with the volume of several hundreds cubic meters have also been built.
