FIELD: welding processes. SUBSTANCE: installation includes the chamber, two cars with covers and two additional driven covers for sealing each end surface of the chamber. Electron beam guns are mounted on the cars. When adjustment operations are being performed in one of the cars, the chamber of the installation is being sealed with the aid of the additional cover, and inside of it welding operations are being realized on the other car. EFFECT: enhanced labor conditions. 1 cl, 2 dwg
