  • Method and apparatus for detecting internal rail defects
    Patent number: 9010186
    Abstract: An ultrasonic rail inspection system designed to detect defects in a rail which result from longitudinal cracks that propagate in the horizontal and transverse plane of the rail. Detection of this type of defect is possible by directing an ultrasonic beam into the rail at a predetermined angle from the perpendicular to the surface of the rail. The predetermined angle must be sufficient to detect these normally undetectable defects and can be in the range of 8° to 14° from the perpendicular.
