The study was broken down into two phases. Phase I consisted of a laboratory investigation of test specimens to determine the reliability of the ultrasonic equipment and testing procedure. Phase II was a field study where the knowledge, skills and abilities gained in the laboratory study were applied to actual fabrication being done for the Louisiana Department of Highways. The testing for both phases of the study was performed in accordance with the American Welding Society Specifications of Welded Highway and Railway Bridges, Ultrasonic Testing of Goove Welds.
A comparison of ultrasonic testing to radiographic testing reveals many advantages of ultrasonic testing. Therefore, it is the recommendations of the investigators that the Louisiana Department of Highways prepare themselves to be capable of qualification of ultrasonic inspectors.
