Abstract:
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.
Abstract:
A pedestal mount capacitive pressure sensor (10) is supported in a housing (11) and used to sense fluid pressures to provide air pressure data relating to the performance of air vehicles. The capacitive sensor uses a thick base plate (40) on which a diaphragm (48) is mounted. A capacitive electrode (52) is mounted to the diaphragm and pressure deflects the diaphragm to provide an output. The pressure sensor (10) is mounted in an outer housing (11) using a stress isolating pedestal (20).
Abstract:
A method and test block (400) for controlling weld penetration depth in a work piece (100) are disclosed. The test block (400) simulates a work piece relative to a welding process of the work piece. The test block (400) includes a test welding path (402). The test welding path (402) replicates a production welding path on a weld surface of the work piece. The test block (400) includes a melt- thru surface that underlies the test welding path (402). The melt- thru surface is spaced apart from the test welding path (402) by a spacing (406) that decreases along a length of the test welding path (402). The spacing (406) varies from more than a standard weld penetration depth to less than the standard weld penetration depth.
