In the automatic inspection system used by the Research Establishment at Risø - described in Part 1 - data (more than half a million per tube) from the ultrasonic dimension measurement and defect inspection are fed into a computer that simultaneously calculates and evaluates the results. This paper described the development of the computer program used and discussed the advantages of computer control over normal analogue recording techniques. The overall benefits gained by using a computer controlled ndt system are outlined.
