The efficiency of using electron beam welding in producing permanent joints of structural materials of all thicknesses
and shapes is well-known. The work for the first time considers the possibility of using electron beam welding for
the production of high-precision parts of optical system in cathode unit, providing the necessary parameters and their
joining with electron beam gun insulator in future. The use of electron beam welding at the final stage of manufacturing
cathode unit opens the opportunity of minimizing the number of further technological operations. It is noted that
to create the welding technology, in which the operation of welding would become a final assembly operation, the
development of new designs of welded joints and schemes for assembly of cathode unit are required. Due to a correct
design of welding units and compliance with the accuracy of assembling for welding, it became possible to preserve
geometric dimensions after electron beam welding and to provide the operational reliability of the design as a whole.
