The method includes identifying a candidate wheel or wheel set, preparing the wheel or wheel set to receive new welding, performing a welding operation on the wheel/wheel set, and performing post-welding steps to ensure the re-manufactured wheel meets a defined profile standard. Preparing the wheel may include cleaning, grinding, and pre-heating one or more surfaces of the wheel.
