Abstract
In a nondestructive ultrasonic testing method for an implementation in a testing device, defects are installed in a testing area of a structural part by determining reflections on inhomogeneities in a testing area of the structural part. At least one ultrasonic transmitter is provided for coupling ultrasonic excitations into the structural part, and at least two ultrasonic receivers are installed for receiving structure responses to the excitations coupled into the structure. A number of testing points are determined and for each testing point and each location of the ultrasonic receivers, expectancy range data are determined and stored for signal forms being implemented in the testing device. When, an inhomogeneity is present in the respective testing point, excitations are reflected thereon and are measured by the respective ultrasonic receiver. The received reflection data are compared with the stored expectancy ranges to determine the location of a defect.
