Abstract
Systems and methods for determining rate of corrosion in pipes and other structures are disclosed herein. In one embodiment, a method for measuring a rate of corrosion progress in a specimen includes: generating a first initial pulse into the specimen by an ultrasonic transducer, and acquiring a first reflected waveform from the specimen. The first reflected waveform includes a first reflection of the first waveform and a second reflection of the first waveform. The method also includes generating a second initial pulse into the specimen by the ultrasonic transducer. The first initial pulse and the second initial pulse are separated by a time period. The method also includes acquiring a second reflected waveform from the specimen. The second reflected waveform includes a first reflection of the second waveform and a second reflection of the second waveform.
