FIELD: process engineering.
SUBSTANCE: invention relates to electron beam welding units used for high-quality vacuum welding of microwave instrument units and parts. Proposed unit comprises vacuum chamber with vacuum system. Vacuum chamber houses indexer and optoelectronic system with triode electronic gun arranged there above. Said optoelectronic system can displace vertically and horizontally relative to indexer. Detachable diaphragm is arranged between cathode and gun focusing electrode. Gun second anode is equipped with tight video camera and illumination system fixed thereto. Optical prisms are arranged on holder inside said second anode. Aid holder has opening for beam path and can displace in horizontal direction. Said indexer supports parts holders than can inclined through 0° to 90° and turn periodically. Vacuum system incorporates oil-free pumps.
EFFECT: high quality, reliability and efficiency of microwave instrument small parts.
