description The application relates to a method for testing a workpiece using ultrasound in a curved region of the surface of said workpiece, having the following steps: a plurality of ultrasonic signals are emitted from a plurality of transmitting positions into the workpiece a corresponding ultrasonic echo signal is received for each ultrasonic signal the ultrasonic echoes having amplitudes representing local maxima are determined for each transmitting position if an individual ultrasonic echo having an amplitude representing a local maximum was determined for a transmitting position in, the associated ultrasonic echo signal of said echo is selected if a plurality of ultrasonic echoes having an amplitude representing a local maximum were determined for a transmitting position, ultrasonic echo signals are selected if only an individual ultrasonic echo having an amplitude representing a local maximum was determined for an adjacent transmitting position at least the selected ultrasonic echo signals are evaluated.
