In a method and device for ultrasonic testing of a workpiece, a multiplicity of ultrasonic testing pulses are launched into the workpiece from a test surface thereof. At least two ultrasonic testing pulses are launched into the workpiece to be tested at launching points that are spaced apart from one another by a test step width measured along the test surface. A single measured value (&#x12a;) assigned to a local point located in the workpiece is calculated on the basis of the received signals assigned to the at least two ultrasonic testing pulses.

Method and device for ultrasound testing

A method and a device for the ultrasonic testing of a workpiece having an uneven surface is provided. An ultrasonic test head containing a multiplicity of transducer elements arranged rigidly in a linear array, is acoustically coupled to a workpiece. The ultrasonic test head can be driven in a time-delayed manner with a delay time predetermined for each transducer element. The propagation time of an ultrasonic signal transmitted by an individual transducer element and reflected from the surface and received by this transducer element is measured for a number of the transducer elements and is used for correcting the delay times. The transducer elements are subsequently driven with these corrected delay times.
