Abstract
Certain embodiments of the disclosed technology provide systems and methods for an improved header and corresponding port associated with a transducer assembly. The header and port define mating threaded portions, thread stop portions, and a weld gap region. The thread stop portions are configured to mate and maintain a pre-loading tension between the threaded portions during and after applying a weld in the weld gap region. The weld gap region is configured to have a predetermined gap distance such that the weld seals the transducer without stress in the weld. The mating of the first and second thread stops are configured to maintain at least a portion of the pre-loading tension.
Claims20
A transducer assembly, comprising:
- a header assembly, the header assembly including:
- a first thread stop having a first thread stop surface;
- and
- a first weld interface surface;
- a port assembly, the port assembly including:
- a second thread stop having a second thread stop surface, the second thread stop surface configured to mate with the first thread stop surface of the header assembly;
- and
- a weld gap region defined by the first weld interface surface of the header assembly and the second weld interface surface of the port assembly, wherein the weld gap region is configured to have a predetermined gap distance between the first and second weld interface surfaces when the first thread stop surface is in mating contact with the second thread stop surface.
A method, comprising:
- providing a header assembly, the header assembly including:
- a first thread stop having a first thread stop surface;
- and
- a first weld interface surface;
- providing a port assembly, the port assembly including:
- a second thread stop having a second thread stop surface, the second thread stop surface configured to mate with the first thread stop surface of the header assembly;
- attaching the port to the header such that the second thread stop mates with first thread stop and a weld gap region is defined, the weld gap region defined by the first weld interface surface of the header assembly and the second weld interface surface of the port assembly, wherein the weld gap region is configured to have a predetermined gap distance between the first and second weld interface surfaces when the first thread stop surface is in mating contact with the second thread stop surface;
- mating the header assembly with the port assembly;
- and
- welding a portion of the header assembly to a portion of the transducer port assembly at the weld gap region.
