Abstract
A method of manufacturing an undercarriage track joint assembly includes forming at least a first portion of a seal assembly by laser brazing an annular, metal sealing washer to a first track link of the undercarriage track joint assembly. The method may also include performing the laser brazing to form at least one of an annular fillet of braze material between the first track link and at least a portion of an inner diameter surface of the washer and an annular fillet of braze material between the first track link and at least a portion of an outer diameter surface of the washer. The method may still further include inserting a second portion of the seal assembly into a counterbore formed in an axial face of a second track link of the track joint assembly such that an axial sealing face of the washer opposite from the first track link slidably engages with the second portion of the seal assembly on the second track link of the track joint assembly to form a sealing surface between the first and second track links.
