US Patent 7467940 System and Method for Joining Non-Compatible Components

An improved nozzle apparatus and method of manufacture are provided in which non-compatible components (such as a metallurgically non-weld-compatible nozzle tip and seal) may be secured/attached. For example, the apparatus and method may comprise securing a seal between a first portion of a nozzle tip and a retention ring. The retention ring may comprise a material that is weld-compatible with the nozzle tip and may be welded to the nozzle tip whereas the seal may be non-compatible with the nozzle tip. As a result, the materials of the nozzle tip and the seal may be chosen substantially without regard to their compatibility.
