Computers in ultrasonic NDT

The paper reviews the various aspects of the development of ultrasonic NDT techniques made possible by the use of computers. Computerised control of scanning rigs, data collection, analysis and display are described. The advantages of whole waveform collection and analysis are discussed, as are some of the associated problems and their solutions. It is concluded that the use of computers has added flexibility in the use of equipment, it has permitted optimisation of the scanning of specimens, offered greater data storage possibilities and given greater scope in the analysis and display of data
