Gas pressure welding is commonly used for rail welding in Japan. This technique however requires specialist skills for the rail-end surface grinding stage and the rail heating process using a burner. In anticipation of a decrease in the number of skilled welders, a new simplified and standardized gas welding method with minimal requirement for expert training has therefore been studied and developed.This paper describes the newly developed gas pressure welding process, and presents the performance test results of the gas pressure welds prepared according to this process.
