Abstract

1424636 Welding by pressure GOSUDARSTVENNY NAUCHNO - ISSLEDOVATELSKY INSTITUT TEPLOENERGETICHESKOGO PRIBOROSTROENIA 18 June 1974 [18 June 1973 (2)] 27017/74 Heading B3R [Also in Divisions G1 and G3] In a pressure gauge in which a corrosive liquid under pressure (Divisions G1, G3) operates against a diaphragm 2<SP>1</SP>, the diaphragm is made in two layers of material, such as tantalum and a precipitation-hardened steel bonded together by diffusion welding.
