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 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,

In Japan, a majority of steel bars are welded by the gas pressure welding because it is superior to other joining methods in workability. In the Hyogoken-Nanbu earthquake on January 17, 1995, a number of gas pressure welds in reinforced concrete memb
