In Japan, four welding processes have been generally adopted for producing continuous welded rail (CWR): flash welding (FW), gas pressure welding (GPW), enclosed arc welding (EAW), and thermit welding (TW). Thermit welding method is the most popular

Gas pressure welding (GPW) is a solid phase welding method. This method is commonly used for rail welding in Japan. However, there is concern that the supply of acetylene gas, which is used as the fuel gas in the conventional GPW system, will cease d

Gas pressure welding method is often applicable for joining of rails and reinforcing steel bars. However, if bonding work is inferior, a large quantity of oxide inclusions remain at the weld interface and those inclusions will cause the weld defects.

Although improvements in ultrasonic inspection methods have brought about a reduction in the incidence of alumino-thermic weld failure, some failures still occur in the early stages after installation of weld as a result of solidification cracks. It

Gas pressure welding method does not need heavy equipments, and produces highly reliable joints. Therefore, it is often used for rails and reinforcing steel bars. However, if bonding work is poor, a large quantity of oxide inclusions remain at the we

Thermite welding is widely used in the world. In the Japan railway company group, the application ratio of this method is approximately 40 % every year. The reasons why the thermite welding method is widely used are that the equipment has good mobili

In Japan, four types of welding methods, that is, flash welding, gas pressure welding, enclosed arc welding and thermite welding are applied to rail welding. All welds are inspected by nondestructive inspection right after welding in order to assure

In the Japan railway company group, rails are welded at over 50,000 points every year, of which those welded by the gas pressure welding (GPW) method account for approximately 30 %. Because gas pressure welds have as good performance as flash welds,

This paper studies the type and causes of damage to rail welds, which are most often suffered by thermite welds. It analyzes all damaged welds from 1985-2001, noting that a total of 121 failed. Thermite welds most often (90%) failed because of transv
