A pressure transducer assembly, and a method of making the same, comprising a header having a first connection portion; a port having a corresponding second connection portion, wherein the first connection portion of the header is attached to the second connection portion of the port to create a header-port interface; and an integral back up ring defined in one of the header and port, wherein the integral back up ring is separated from the header-port interface by a cavity. The first connection portion of the header is attached to the second connection portion of the port by a full penetration weld and the integral back up ring is adapted to block the full penetration weld from damaging the header and thus minimize, if not eliminate, crack propagation.
