This document specifies the application of the (semi-) automated phased array technology for the semi-, or fully- automated ultrasonic testing of fusion welded joints in metallic materials equal to and above 6 mm thickness. It is intended for use on full penetration welded joints of simple geometry in plates, pipes, and vessels, where both the weld and parent material are low alloyed carbon steel. Where material dependent ultrasonic parameters are specified in this standard they are based on steels having an ultrasonic sound velocity of (5920 ± 50) m/s for longitudinal waves, and (3255 ± 30) m/s for transverse waves. This has to be taken into account when examining materials with a different velocity. The document provides guidance on the specific capabilities and limitations of phased array technology for the detection, location, sizing and characterisation of discontinuities in fusion welded joints. Phased array technology may be used as a stand-alone technology or in combination with other NDT methods or techniques, for manufacturing inspection, pre-service and for in-service inspection. The document specifies four testing levels, each corresponding to a different probability of detection of imperfections. This document permits assessment of indications for acceptance purposes based on either amplitude and length or height and length. This document does not include acceptance levels for discontinuities.
