Description

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 of 6 mm. This document applies to full penetration welded joints of simple geometry in plates, pipes, and vessels, where both the weld ant the parent material are low-alloyed carbons tell. This document makes reference to ISO 16828 and provides guidance on the specific capabilities and limitations of TOFD for the detection, location sizing and characterization of discontinuities in fusion weld joints. 4 testing levels (A,B,C,D) have been specified in accordance with ISO 17635 and corresponding to an increasing level of testing reliability.Guidance on the selection of testing levels is provided but this document does not include acceptance levels for discontinuities.
