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.
