Four welding methods are used for rail welding in Japan. In the last 17 years, over 100 welds were damaged, of which those welded by the thermite welding method and the enclosed arc welding method account for about 70%. This report describes the analysis results of the forms and causes of damaged rail welds. We believe that these analytical results will contribute to the improvement of the reliability of rail welds in the future.
