The cracking was made on web of U75V rail end by electric spark and high frequency fatigue,the surface of crack macrostructure and decarboniztion was tested after flash welding,it point out that artificial crack macrostructure and microstructure differentiate of other level crack on web of rail after flash welding. It offer gist for quality test and verdict of level crack on web of rail after flash welding joint.
