Abstract

A method for the nondestructive testing of pipeline, and internal or external coatings, using guided ultrasonic waves excited from the inside or outside diameter, wherein at least two transducers are employed to send and receive ultrasound, wherein a data normalization scheme is employed to account for transducer variability, and wherein the hardware arrangement has a number of pulser channels and a number of receiver channels for the collection and storage of signals.
