摘要：
A method and apparatus for detecting and regulating a focused condition of an electron beam emitted from an electron gun of an electron beam welding apparatus. An electron beam of a low intensity is first directed onto the workpiece. The coil current of an electromagnetic condenser lens used to focus the electron beam is then varied linearly. The resulting electrons and other radiation produced from the workpiece as a result of this irradiation is then sensed and a signal corresponding to the intensity thereof is produced. The focus position of the electron beam is determined in accordance with variations in this signal.
