Paper Title:
Research on the Failure Mechanism of Flash Welded Rail
  Abstract

For the high speed train, safety is the most important factor. Flash welding is the primary technology for the seamless line rail in Chinese railway. So the quality of the flash welded joints is the most important. This paper presents the situation of joint fracture in rail flash welding joints and analyses the failure mechanism through macroscopic and microscopic observation. The result demonstrate that the cracking of the rail is fatigue-crack propagation,the fatigue cracking is caused by alumina calcium-Aluminates-non-metallic inclusion.
