Abstract: An inspection device for inspecting tangential recesses in a rotor disk by means of eddy currents is disclosed. The device includes a probe containing a plurality of sensors arranged to acquire a plurality of data series during a scan stroke, and the probe is mounted on moving equipment that is slidable in a support that is provided with two positioning members for co-operating with recesses neighboring the recess for inspection.

Abstract: One or more phased array ultrasonic probes in the shape of conical section arcs, or an entire conical section ring, emit beams at a fixed incident angle with respect to the outer surface of a tube or pipe under inspection. At any given moment, these beams strike the tube at a single small entry zone from number of different directions. After being refracted at the inspection angle corresponding to the fixed angle of incidence, defects having longitudinal, transverse and oblique orientations are detected in the three-dimensional volume of the tube wall. The number of entry zones required for complete coverage of the outer surface of the tube is a function of the size of the tube, the speed at which it passes through the inspection station and the rate of rotation of the tube.
