MODEL 101
UNIVERSAL MACHINE FOR ELECTRON BEAM WELDING

• Universal production machine for EBW of a wide range of cylindrical and flat workpieces.
• CNC+PLC of all machine systems.
• Real-time seam tracking and monitoring of EBW process by RASTR-3 system on the basis of the secondary electron emission.
• Power source with the electron tube flashless system.
• 5, 15, 30 or 60 kW electron beam gun and power source at 60 kV.

 APPLICATIONS

• Welding of high frequency structures.
• Welding and repair in turbine engine fabrication.
• Selection of welding technology for a wide range of workpieces.

 MACHINE DESIGN

• Work chamber has two sliding doors. For loading and unloding, the workpiece table is moved out of the work chamber onto the runout platform. This is especially necessary for welding of a large heavy workpieces with commensurately large clamping devices. The table accommodates a 2-axis-manipulator for welding of flat workpieces or a rotator for circular welding. The electron beam gun with an optical viewing system is mounted on one of the three openings on the upper cover of the chamber.
• The gun has an independent turbomolecular pumping system. The cathode area is isolated by the column vacuum valve to keep the gun under vacuum when the work chamber is vented. The precision of the guidance and drive sysems equals that of the high-precision machine tools operation with tolerances in the hundredth-of-a-millimeter range.
