Method for Creating an Evaluation Table for an Ultrasonic Inspection and Method for Ultrasonic Inspection

A method for the ultrasonic inspection of an object, the method comprising:

• radiating ultrasound onto at least one volume element of the object;
• acquiring at least one ultrasound reflected from the volume element because of at least one defect;
• determining the reflectivity by means of the absolute value of a time-dependent amplitude of the reflected ultrasound for the volume element;
• and
• ascertaining a defect size associated with the determined reflectivity by means of an evaluation table created by:
• simulating a scattering of ultrasound on a defect having an established defect size using a computer-implemented two-dimensional or three-dimensional simulation, wherein the defect size is less than or equal to the wavelength of the ultrasound and the simulation takes into consideration a mode conversion of the ultrasound by the defect;
• ascertaining the reflectivity of the defect from the simulation;
• and
• creating the evaluation table by means of an assignment of the ascertained reflectivity to the established defect size of the defect.
