Advances in microcomputers in the last decade have resulted in the advent of computer-controlled field ultrasonic systems adapted to many requirements in modern industry. Integrated, automated scanner and ultrasonic systems are now available that gather wall thickness readings frequently enough to generate an accurate definition of the remaining thicknesses of corroded components. Not only does this automated ultrasonic system provide a method of on-line corrosion monitoring, but also it allows the analyst to determine the mechanical integrity of the corroded part. The capabilities of the system are discussed and a comparison of the data with the data generated by conventional, manual ultrasonic testing is made.
