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 (&#x3b1;), 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 ().
