ABSTRACT:
A method for ultrasonically inspecting the surface of a bore, particularly the bore of a railroad wheel axle, includes the step of generating a transverse ultrasonic wave from an emitter which interacts with the surface of the bore, and comparing the amplitude of the echoes obtained with values obtained from a calibration curve plotted for a bore having a standard defect which corresponds to the bore to be inspected so as to determine the existance of a defect when the amplitude of the echoes is greater than a specified fraction of the value indicated by the calibration curve. A corresponding device is provided for ultrasonically inspecting the surface of the bore of the railroad wheel axle.
