  • Re-manufacture and apparatus of worn railroad freight car and locomotive wheels by rotational continuous longitudinal welding
    Patent number: 9434019
    Abstract: A method for re-manufacturing a worn railroad car wheel is described herein. 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.

  • Process for rail restoration and rail manufacture using welding
    Patent number: 8367960
    Abstract: A method for restoring a worn rail section includes cleaning a worn surface of a rail section to expose a clean metal surface, heating the rail section to a first temperature before welding, welding new metal on the clean metal surface of the rail section after heating the rail section to the first temperature, heating the rail section to a second temperature after the welding to heat-treat a heat-affected area caused by the welding, and shaping the rail section, wherein the welding is performed by a gas metal arc welding (GMAW) process.
