DIFFUSION WELDING INSTALLATION Russian patent published in 1994 - IPC

FIELD: radio-technical industry branch. SUBSTANCE: installation has a packing apparatus, including an upper and lower plates, mounted on a tensioning member, being in the form of electrically conductive tubes with end flanges, isolated by high temperature insulators. The installation is provided by pressure current supplying rods, having guiding sleeves, springs and pins, which transfer welding effort and high voltage through washers onto parts, being welded. Cartridges with for parts are mounted on the lower plate; the cartridges are arranged coaxially with a symmetry axis of the installation and they include supporting foot, changeable centering sleeve or metallic ring and dielectric collars. Electrically conductive spring-loaded washers and platforms with end cam members are mounted between the plates. The packing apparatus, mounted on an annular platform, is arranged in a vacuum chamber and is provided by buses, latches and insulators. The welding is being performed in an electrostatic field. EFFECT: enlarged manufacturing possibilities of diffusion welding process. 2 cl, 3 dwg
