Prediction of the Tolerable Defect Size for Strain Based Design
By using data of Curved Wide Plate (CWP) tests, a simple procedure to derive tolerable girth weld defect sizes is presented. The procedure involves prediction of the maximum tolerable defect size as a function of the applied remote plastic strain and the actual pipe and weld metal properties. Application of the methodology requires a reliable non-destructive testing technique that can detect the critical defect dimensions.
