Method and apparatus for electron beam welding

A method and an apparatus for electron beam welding, in which the oscillation of the focus of an electron beam which is due to the pulsation of a direct-current high voltage for accelerating electrons is detected, and the electron beam is controlled according to the detected oscillation of the focus...
