Abstract
An ultrasonic system was developed for flaw type identification and severity assessment and corrosion pitting mapping during submarine pressure hull inspection. It provides computer-aided assistance to an inspector during manual ultrasonic inspection. The system provides inspection record keeping and management. Feedback from laboratory technicians and submarine pressure hull inspectors was taken into account in the final design of the system software. For flaw type identification and severity assessment, the unit was used to collect data from different types and sizes of flaw from actual submarine pressure hull cut-out strips. These data were analyzed and sorted using the Tektrend Intelligent Classifier Engineering Package (ICEPAK) for flaw severity quantization as well as for flaw type identification. Classifier designs and the results of their use will be presented.
