Analysis of Damaged Rail Weld

Yoshihiro TERASHITA, Mitsumasa TATSUMI


  Four kinds of welding methods have been applied to rail welding in Japan, and, over 100 welded parts were damaged in the last 16 year. Among them, those welded by the Alumino-thermic welding method and the Enclosed-arc welding method account for about 70% of all. This report describes the analysis results of damage form and damage factors of each weld. We believe that these analysis results contribute to an improvement of reliability of rail welded parts in the future.
