Abstract
Occurrence of overvoltages in output circuits of a high-voltage power source, cable and welding gun after its discharge was studied using computer modeling. Recommendations are given on optimal parameters of elements of the overvoltage limitation circuit for the powerful power sources.
 
 
Keywords: electron beam welding, electron gun, source of accelerating voltage, limiting resistor, natural inductance, shunting diode, high-voltage cable, discharge in gun, modeling of transition processes
