✦ Synopsis

Reliability of non-destructive examination of welded joints

Dept. Civil engineering, Imperial College London, CESLIC Report OR7,74 pp. (Feb. 1989) This report reviews published information from several national and international programmes on detection probabilities and sizing errors. Currently used functions for 'failure to detect' probabilities are critically reviewed and new generalised models are proposed for use in updating defect size and occurrence distributions. It is shown that most of the models currently used by industry have not been rigorously fitted to the available data and, furthermore, are unconservative for large defects.
