Fuel injector with weld integrity arrangement

摘要

A fuel injector (10) assembly with fluid communication cut-outs is disclosed which includes a method of forming a fuel injector that allows weld integrity evaluation between a shell (60) and a body (42) of the fuel injector, the fuel injector having a fuel inlet (16), a fuel outlet, a fuel passageway extending from the fuel inlet to the fuel outlet along a longitudinal axis, the body having an exterior surface, and the shell having an interior surface, the method including the steps of securing the shell (60) to the exterior surface of the body (42), and cincturing the exterior surface of the body with the interior surface of the shell such that fluid communicates between the exterior surface of the body and the fuel passageway for particular weld integrities.
