Abstract
The electron beam welding installation of the universal type ELU-20, designed by National Institute of Aviation Technologies (NIAT, Russia), in most cases does not provide meeting the modern requirements, specified to the technology and equipment. On order of users the E.O. Paton Electric Welding Institute developed and created specialized complex for EBW with automatic systems of control and application of distributed computer systems on the base of the installation ELU-20. Such approach allowed realization of a number of technological capabilities on automatic control of parameters of welding electron beam, programmable movement and inclination of electron beam gun, visual programming of trajectory of a butt in the real time mode, during the operation of vacuum system of pumping-out. «Windows» as the oriented interface of the user provided graphical plotting and editing of programs for welding, 3D display of specimens of the product and trajectories of the butt during welding process. 2 Ref., 3 Figures.
 
 
Keywords: electron beam installation, vacuum chamber, electron beam gun, pumping-out system, coordinate axes of movement, inclination and rotation, computer control, interface, video monitoring, focusing, programming of butt trajectory, master-program, cutoff voltage
