The split-method of ultrasonic nondestructive testing

This article describes a new method of echo-impulse ultrasonic testing based on a new split-algorithm for signal formation and processing. Application of a split-algorithm can significantly raise the sensitivity of testing devices (by two-three or more orders) while avoiding the loss of resolving capacity. Experimental results prove the practical importance of split-algorithms. Due to its high sensitivity, the proposed flaw detection method can be used to test objects with high absorption of ultrasound.
