Abstract: 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 (?) 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.

Abstract: A method performs ultrasound testing of a test body having a hole extending in an axial direction. The method include disposing a test head within the hole. The test head extends in the axial direction and has sensor rings which are at a distance from one another and are disposed one behind the other in the axial direction. The sensor rings have a plurality of ultrasound transducers which are at a distance from one another. The ultrasound transducers disposed in a segment of each of the sensor rings extend in a circumferential direction of a respective sensor ring on at least a subsection of a circumference of the respective sensor ring. An ultrasound test pulse is injected into the test body. Measured values of first and second echo signals are evaluated to determine at least one of a location or an orientation of a fault in the test body.

Abstract: Device for volumetric testing of pressure-vessel walls and pipes with a combined transmit-receive test head for scanning a test track having a given test-track spacing, includes an oscillator unit including an oscillating crystal and a receive oscillating crystal having respective centers spaced apart a distance smaller than that of the test-track spacing so that the test head has a full width within which at least one additional oscillating crystal is accommodated, the additional oscillating crystal being paired with one of the transmit and receive oscillating crystals so as to form therewith another oscillator unit including a transmit oscillating crystal and a receive oscillating crystal having centers spaced apart a distance smaller than that of the test-track spacing, the distance between the crystals of both of the oscillator units being substantially equal.
