DIFFUSION WELDING PRESS Russian patent published in 2004 - IPC

Abstract RU 2238829 C1

FIELD: mechanical engineering; welding equipment.

SUBSTANCE: invention relates to diffusion welding equipment, mainly, to presses designed for building compressive force on surfaces at diffusion welding temperature. Proposed press has hermetically sealed chamber filled with working medium and two movable opposite walls. Movable walls of press are made in form of disks arranged coaxially with clearance. Two ring diaphragms are installed between disks. Inner edges of diaphragms are interconnected by permanent joint, and outer edges of each diaphragm are connected with one of disks also by permanent joint. Invention makes it possible to create minipress comparable with dimensions of blanks to be welded.

EFFECT: provision of independent and automatic compressing of blanks at diffusion welding temperature.
