  1. Electron-beam welding was developed by the German physicist Karl-Heinz Steigerwald [de] 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]

  2. Since the mid-20th century, electron-beam technology has provided the basis for a variety of novel and specialized applications in semiconductor manufacturing, microelectromechanical systems, nanoelectromechanical systems, and microscopy.

  3. The physicist Dr. h.c. Karl-Heinz Steigerwald built the first electron beam processing machine. What had to be laboriously worked out at that time is taken for granted today. The history of electron beam technology began with the experiments by physicists Hittorf and Crookes.

  4. The history of electron beam technology began with the experiments by physicists Hittorf and Crookes, who first tried to generate cathode rays in gases (1869) and to melt metals (1879).

  5. 1 sie 2016 · The first electron beam drilling experiment of an unintended hole of Ø 7 μm in a platinum aperture, as well as the first electron beam welding actually bead on plate by K.H. Steigerwald were carried out in 1949 [1].

  6. Electron beam welding dates back to January 1951 when an electron device for perforation was patented, and to September 1951 when electron beam welding was patented in Great Britain [1].

  7. 21 kwi 2020 · Developed in France, the electron beam welding process uses a focused beam of electrons as a heat source in a vacuum chamber. J.A. Stohr of the French Atomic Energy Commission made the first public disclosure of the process on Nov. 23, 1957.
