Patent ID: 6923067

Claim:
A method for testing solid bodies using guided ultrasonic waves, comprising: producing a first guided ultrasonic wave in a solid body by means of an ultrasonic transmitter, the first guided ultrasonic wave having a first mode; detecting reflection waves of the first guided ultrasonic wave by an ultrasonic receiver; producing a second guided ultrasonic wave in the solid body by means of the ultrasonic transmitter, the second guided ultrasonic wave having a second mode; detecting reflection waves of the second guided ultrasonic wave by the ultrasonic receiver; determining structures of defects in material of solid body by combination of detected values of the reflection waves of the first guided ultrasonic wave and the second guided ultrasonic wave; and accelerating and evaluation of a defect by converting all reflection values of the reflection values of the reflection waves in an expected region into defect values before measurement and wherein measurement comprises a comparison of the measured reflection values with previously calculated values.
