Title
(EN) EXPLOSION WELDED TRANSITION JOINT FOR A PRESSURE TRANSMITTER
(FR) JOINT DE TRANSITION SOUDE PAR EXPLOSION POUR MULTIPLICATEUR DE PRESSION
Abstract
(EN)
A weld ring (30) for a pressure transmitter (11) welded to a corrosion resistant material (18) at one section (40) of the ring, and welded to a different material at a second section (42) of the weld ring (30). The sections (40, 42) of the weld ring (30) are made of different materials compatible with the materials to which they weld. The sections (40, 42) of the weld ring (30) are explosion welded together to provide a pressure tight, highly reliable interface bond between the two sections (40, 42). The materials of the two sections (40, 42) are essentially incompatible for high temperature fusion welding.
(FR)
Bague de soudage (30) pour multiplicateur de pression (11) soudée à un matériau résistant à la corrosion (18) au niveau d'une de ses sections (40) et soudée à un matériau différent au niveau d'une deuxième de ses sections (42). Les sections (40, 42) de la bague de soudage (30) sont fabriquées en matériaux différents et compatibles avec les matériaux auxquels elles sont soudées. Ces sections (40, 42) sont soudées réciproquement par explosion, afin de constituer entre elles un joint étanche aux faces de contact extrêmement fiables. Les matériaux des deux sections (40, 42) sont essentiellement incompatibles pour un soudage par fusion à température élevée.
