Abstract (en)

[origin: WO2020001671A1] The invention relates to a method for nondestructively acoustically examining at least one region (I) of a component (10) of a turbomachine, wherein at least the following steps are performed: a) arranging a transmitter (12) comprising a plurality of individual oscillators on the region (I) of the component to be examined, b) introducing at least one ultrasound beam (16) into the component (10) by means of the transmitter (12), c) receiving at least one ultrasound beam (18) reflected by the component (10) by means of a receiver (20) comprising a plurality of individual receivers, and d) checking, on the basis of the received ultrasound beam, whether there is a deviation in the region (I) of the component (10) which characterizes a segregation. The invention further relates to a device for carrying out a method of this type.
