THREAD TENSIONING MEMBER IN WELDED HEADER STRUCTURE

摘要

An improved header assembly and corresponding port assembly comprising a tensioning member, wherein the tensioning member is isolated and separate from the weld portion and is adapted to place a threaded portion between the header assembly and port assembly in tension and maintain such tension, and thus relieve tension from the weld, before and after welding, thereby increasing the lifespan of the header and port assemblies.

主权项

1. A method, comprising:
providing a header assembly comprising a first threaded portion; providing a port assembly comprising a second threaded portion configured to mate with the first threaded portion of the transducer header assembly; providing a tensioning member adapted to maintain tension between the first threaded portion and the second threaded portion; mating the header assembly with the port assembly by engaging the first threaded portion with the second threaded portion; pre-loading, by the tensioning member, a tension between the first threaded portion and the second threaded portion; and securely connecting, while maintaining pre-loading tension, a portion of the header assembly to a portion of the transducer port assembly at an interface between the header assembly and the port assembly.
