Thanks to higher quality, rail now stays in service longer, so determining better in-track welding procedures and protocols is more critical.
Joining rails in track through welding is a job that the North American freight railroads perform several hundred thousand times a year, at a cost of several hundred million dollars a year.
As rail quality and service life improve, so does the need for better field welds. Welding processes currently used are not entirely satisfactory in cost, track time required and service life. Consequently, the Transportation Technology Center, Inc., a subsidiary of the Association of American Railroads, is doing research and ...
