A method and system for inspecting a rail profile include using ultrasonic phased arrays. Determined anomalies, such as material flaws like volumetric defects and cracks, in a fluid-immersed rail profile are detected by employing one or more phased array probes located proximate the rail profile. Electronic delays and beam steering and focusing can be employed to tailor the inspection to the rail geometry.

A method and a device for the near-surface, non-destructive inspection by means of ultrasound of a rotationally symmetric workpiece having a diameter that changes from section to section are provided. The method and device are based on the insonification of an ultrasonic test pulse into the workpiece at a defined insonification angle and the subsequent recording of an ultrasonic echo signal from the workpiece. Echo signals that trace back to a near-surface region ROI of the workpiece are identified and evaluated. Then, a graphic representation of the surface of the workpiece is generated.
