This document specifies the application of the time-of-flight diffraction (TOFD) technique to the semi- or fully automated ultrasonic testing of fusion-welded joints in metallic materials of minimum thickness 6 mm.<\/p>\n

It applies to full penetration welded joints of simple geometry in plates, pipes, and vessels, where both the weld and the parent material are low-alloyed carbon steel. Where specified and appropriate, TOFD can also be used on other types of materials that exhibit low ultrasonic attenuation (especially that due to scatter).<\/p>\n

Where material-dependent ultrasonic parameters are specified in this document, they are based on steels having a sound velocity of (5 920 \u00b1 50) m\/s for longitudinal waves and (3 255 \u00b1 30) m\/s for transverse waves. It is necessary to take this fact into account when testing materials with a different velocity.<\/p>\n

This document makes reference to ISO 16828<\/span><\/span> and provides guidance on the specific capabilities and limitations of TOFD for the detection, location, sizing and characterization of discontinuities in fusion-welded joints. TOFD can be used as a stand-alone method or in combination with other non-destructive testing (NDT) methods or techniques, for manufacturing inspection, and for in-service inspection.<\/p>\n

This document specifies four testing levels (A, B, C, D) in accordance with ISO 17635<\/span><\/span> and corresponding to an increasing level of testing reliability. Guidance on the selection of testing levels is provided.<\/p>\n

This document permits assessment of TOFD indications for acceptance purposes. This assessment is based on the evaluation of transmitted, reflected and diffracted ultrasonic signals within a generated TOFD image.<\/p>\n

This document does not include acceptance levels for discontinuities.<\/p>\n","protected":false},"excerpt":{"rendered":"
