Abstract

A device for destruction-free testing of ferromagnetic component walls such as pipe walls or panel walls with respect to cracks or other elongate defects by ultrasound waves, in particular shear waves, that are excited in a wall area magnetized in a predetermined magnet orientation by a high frequency induction coil, that propagate on a path that can be oriented by an induction coil as a sending transducer, and that are received at a spacing from the sending transducer by at least one induction coil as a receiving transducer, is designed in such a way that defects of a predetermined shape, in particular cracks resulting from stress crack corrosion, can be detected well without this requiring increasing the construction expenditure and the energy expenditure of the device inappropriately.
