Abstract
The object of the invention is a method for the non-destructive testing of workpieces (14) or components with ultrasonics and a device for applying the method. The workpieces (14) are subjected in accordance with the through-transmission principle at the same locations (38) in succession with ultrasonic waves that differ by their opposing directions under conditions that are otherwise the same. The ultrasonic signals received in the two different sound directions are, provided they have different signal amplitudes, compared with given values obtained from a similar workpiece with defects in previously known depth in order to determine the depth of defect in the workpiece (14). If the sound absorption is complete, the ultrasonic waves continue to be applied in opposite directions to neighboring positions until ultrasonic signals are received whose differences are evaluated in order to determine the depth of the defect concerned.
