LATEST RAIL WELDING TECHNOLOGY AND ITS RELIABILITY

On Japanese National Railways, welded rail is used on all tracks of the Shinkansen and on the main tracks of the narrow-gauge lines. The welding processes utilized by JNR are flash welding, gas pressure welding, shielded arc welding and alumino-thermic welding. Flash welding and alumino-thermic welding processes are the same as those practiced by other world railways. Gas pressure welding and arc welding are specialized processes developed by JNR. Recently fractures of rail welds have decreased to a minimum on the Shinkansen and only a few occur annually on the narrow gauge lines. JNR rail welding is reviewed.
