Abstract
A composite track link is provided that has a body and a replaceable rail brazed or soldered together to provide a metallurgical bond between the track link body and the rail such that the rail may be removed and replaced by heating the track link or the brazing or soldering filler metal when the rail becomes worn. This process enables the rail to be separated from the body of the track link so a new rail can be brazed or soldered to the body of the track link. As a result, track links or bodies of track links may outlast the rails by multiple use cycles. Further, the body and rail may be formed of different materials.
