- 66 - AUTOMATED ULTRAS<strong>ON</strong>IC TESTING SYSTEMS FOR THE CHARACTERIZATI<strong>ON</strong> OF DEFECTS IN WELDMENTS M. Macecefe, K. Lu&cott, 3. Wells, Techno Scientific Inc., Voioniview, Ontario V.K. Mafc CAWMET, Ottama, Ontatio ABSTRACT An ultrasonic immersion inspection system, intended for research work on large, heavy section we laments, has been built. During its design special attention was given to three factors. First was the capacity and rigidity of the mechanical scanner and immersion tank. Second was the importance of flexibility in the data acquisition subsystem, to support a number of different data collection modes. Finally, there was a desire to provide the operator with a variety of display methods for test data. The resulting system provides for simultaneous collection of up to 8 channels of ultrasonic data, and allows digitization and storage of ultrasonic waveforms. Processing of the collected data is performed by a general purpose microcomputer, with test results displayed using interactive 3-d'' n ension colour graphics. It is expected that future work will involve the addition to the system of more advanced algorithms for the location and sizing of weld defects.
