A method for testing a component non-destructively, particularly for internal defects, includes the following steps: a) providing a rotationally symmetrical component having a plurality of preferably cylindrical recesses, which are arranged at one or more hole circles, b) arranging a transmitter probe serving as an ultrasound transmitter and a receiver probe serving as an ultrasound receiver spaced apart from each other outside the component such that ultrasound waves can be irradiated into a shaded area located behind one of the recesses in the component by the transmitter probe and ultrasound waves which are diffracted at least at one defect present in the shaded area can be received by the receiver probe, and c) using time of flight to determine whether one or more faults are present in the shaded area. An apparatus carries out such a method.

Method and device for testing a component non-destructively

A measuring assembly for detecting the wall thickness of a pipe, including an ultrasonic probe and a testing head with a main element which receives an ultrasonic probe and the lower face of which defines a main element support surface is provided. The testing head has two wing elements, the lower face of each of which defines a wing element support surface and which are held on the main element in a pivotal manner about pivot axes extending substantially parallel to one another in a longitudinal direction such that the wing element support surfaces can be moved towards each other and away from each other. The wing elements are connected via synchronizing means such that the pivotal movements of the wing elements about the corresponding pivot axes are carried out in a synchronous manner. An associated method is also provided.
