Control unit for power supply and beam forming system for electron beam welding installation

Abstract: The article presents development results of control unit for power supply and beam forming system. This system is intended for thermocathode electron gun in an electron–beam welding installation. The electronic unit is implemented on a modern technological basis using digital-analogue conversion technology and provides functions to control different parameters. These parameters are: magnitude of the thermocathode current, currents in beam focusing and deflecting systems, positioning on the weld joint. Control of all the parameters of the electron beam is carried out using a personal computer in automatic and manual modes. This approach allows creating and using technological cards for electron beam welding.
