Abstract
In a method for the ultrasonic testing of a workpiece () in a curved area of its surface, in particular of a workpiece () made of a fiber composite material, an ultrasonic test head () is acoustically coupled to the workpiece in this area, and includes an ultrasonic transducer arrangement () comprising a plurality (N) of individually driveable transducer elements () which are arranged next to one another. In chronologically successive test cycles, a number (n) of transducer elements () are respectively combined to form a group and are driven in a plurality of test pulses within this test cycle in a time delayed manner with respect to one another such that the transmitted ultrasound beam (-) in this test cycle is swept within a predetermined angular range (α), so that one of the number of echo signals, corresponding to the number of test pulses, for each group is received from different directions of the workpiece ().
