Results of analog and microprocessor control of welding electron beam current in modern EBW units are discussed. It is experimentally shown that by improving the control algorithms implemented in a built-in microprocessor, it is possible to lower the value of instability of electron beam current to ± 1 % in the welding mode and to ± 10 % in the mode of low setting-up current (< 1 mA). Generation of current pulses of the required shape and amplitude is ensured for operation of the system of automatic guidance of the beam to the butt during welding
Keywords: electron beam welding, welding electron beam current, NPC system, analog and digital control, noise immunity, fast reaction, accuracy, automatic guidance of the beam to the butt
