Sciaky begins research on a new manufacturing process called Electron Beam Free Form Fabrication (EBFFF) in 2000.. Single VME x86 board W20x0 weld control system In 2007, Sciaky earns a contract with the National Aeronautics and Space Administration's (NASA) Langley Research Center [10] to create a new EB gun system in the U.S. incorporating the EBFFF system and tested on a microgravity ...
Electron-beam welding was developed by the German physicist Karl-Heinz Steigerwald in 1949, [1] who was at the time working on various electron-beam applications. Steigerwald conceived and developed the first practical electron-beam welding machine, which began operation in 1958. [ 2 ]
Since the beginning of electron-beam welding on an industrial scale at the end of the 1950s, countless electron-beam welders have been designed and are being used worldwide. These welders feature working vacuum chambers ranging from a few liters up to hundreds of cubic meters, with electron guns carrying power of up to 100 kW.

The electron beam is a highly efficient power source that can be both precisely focused and deflected using electromagnetic coils at rates well into thousands of hertz. Typical electron-beam welding systems have high power availability, with 30- and 42-kilowatt systems being most common.
The basic components of a typical electron-beam processing device include: [1] an electron gun (consisting of a cathode, grid, and anode), used to generate and accelerate the primary beam; and, a magnetic optical (focusing and deflection) system, used for controlling the way in which the electron beam impinges on the material being processed ...
