A method for testing a workpiece using ultrasound in a curved region of the surface of said workpiece having the following steps: (a) a plurality of ultrasonic signals (14a, b) are emitted from a plurality of transmitting positions (P a-f) at different pivot angles (S a, b) lying in a pivoting range (16a, b) with the aid of at least one ultrasonic transducer (10a-f) and are injected into the workpiece, (b) a corresponding ultrasonic echo signal (18a, b) is received for each ultrasonic signal (14a, b), and the amplitude of the ultrasonic echo produced upon entering the workpiece or on the rear wall of the workpiece is determined, (c) the ultrasonic echoes having amplitudes representing local maxima are determined for each transmitting position (P a-f), characterized by the further steps: if a single ultrasonic echo having an amplitude representing a local maximum was determined for a transmitting position (P a-f) in step (c), the associated ultrasonic echo signal (18a, b) of said echo is selected, if a plurality of ultrasonic echoes having an amplitude representing a local maximum was determined for a transmitting position (P a-f) in step (c), a selection of ultrasonic echo signals (18a, b) is made, provided only a single ultrasonic echo having an amplitude representing a local maximum was determined for an adjacent transmitting position (P a-f) in step (c), by selecting those ultrasonic echo signals (18a, b) which lie in a particular angle range around the corresponding pivot angle (S a, b) of the ultrasonic echo signal (18a, b) having the maximum amplitude of the ultrasonic echo of the adjacent transmitting position (P a-f) and which have an ultrasonic echo having a maximum amplitude, (e) an evaluation is carried out of at least the selected ultrasonic echo signals (18a, b).
