Abstract: A device for destruction-free testing of ferromagnetic component walls with respect to elongate defects has a sending transducer that excites ultrasound waves in a wall area of a ferromagnetic component wall magnetized in a predetermined direction of magnetization. The ultrasound waves propagate on a path oriented by the sending transducer. A receiving transducer receives the ultrasound waves at a spacing from the sending transducer. The configuration of the sending transducer and a high frequency emitted by the sending transducer, which high frequency is to be determined based on a thickness of the ferromagnetic component wall, are selected so as to effect excitation of horizontal shear waves of higher order. The path orientation is selected at a slant angle to the predetermined direction of magnetization. The receiving transducer is positioned lateral to the path and is oriented toward a predetermined testing area of the wall section in the path.
