METHOD FOR MAKING SOLDERED AND WELDED CONSTRUCTION Russian patent published in 2002 - IPC

Abstract RU 2184022 C2

FIELD: manufacture of soldered and welded constructions of different units of power plants with cooled circuit. SUBSTANCE: method comprises steps of making outer wall of construction by welding housing, sphere, branch pipe, cover and carrying members; using one of carrying member including argentum ring; making inner wall of construction in the form of spheric insert; soldering walls at temperature of 1150-1250 C; after cooling quenching them; then pressing argentum ring into carrying member and soldering them in protection medium; subjecting soldered-welded construction to heat treatment, cold treatment and tempering. EFFECT: enhanced operationability of construction in power plant at extremal conditions due to high strength, high fluid tightness and compactness of soldered and welded joints and improved properties of base metal. 1 tbl, 1 dwg
