Ultraschallprüfung verwendet pulsierende Wellen, die auf Metalle submers in Wasser verliehen werden,. The waves penetrate the volume of the part and expose subsurface discontinuities throughout the base. Effective echo is measured as the waves are interrupted when they cross internal discontinuities. The back reflection is used to determine the integrity of the material being tested. Because of this characteristic, Ultraschallprüfung kann auch in Teilen Wanddicke zu bestimmen, nicht leicht meßbar durch Standard-Festmessung verwendet werden,.
