Abstract
An apparatus for non-destructively testing materials by ultrasound and eddy current, which includes an ultrasound material testing device operating in conformity with the electrodynamic converter principle, and also includes an eddy current material testing device. The testing coils of both testing devices are centrally arranged with regard to each other in such a way that the workpiece regions controlled by the testing coils have an at least approximately common central axis. The apparatus furthermore includes a control device which in conformity with the energization of the coil for creating the strong magnetic field for operation of the electrodynamic converter is operable briefly alternately respectively to turn-on and turn-off the respective testing coil of the ultrasound and eddy current material testing device.
