Electron-beam welding plant “ELU-20RZ”

Appointment

Electron-beam welding plant “ELU-20RZ” is made for precision electron-beam welding of circumferential, circular, line welds of parts made of high-strength steels and alloys based on nickel, titanium, niobium, molybdenum, copper, aluminum and dissimilar metal materials of thickness up to 100 mm.


Electron-beam welding plant “ELU-20RZ” allows to eliminate the influence of subjective factors on the welding process by strengthening the streamlined technological process in control program and locking out unauthorized changes to programs. It helps to achieve high stability of technological parameters, to increase the accuracy of mechanical movements, to improve the working comfort of for the operator-welder by integrating computer control system into the workplace. Improving the maintainability of the plant is achieved by automatically diagnosing and testing of the equipment by computer control system.


This plant allows to produce interpolation control of the mechanical coordinates and technological parameters (process current, focus current, deflecting systems currents, etc.);


Plant is equipped with computer control system. In automatic mode it provides control processes for the preparation of vacuum, software control of the welding process, automatic control of the welding mode main parameters, printing of welding technological documentation, which contains the part number, characteristics of the welding process, identified deviations from standard technological parameters, the date and the name of the operator-welder.
