Abstract

This document specifies the approach to be followed when developing procedures for the ultrasonic testing of the following welds: - welds in stainless steels; - welds in nickel-based alloys; - welds in duplex steels; - dissimilar metal welds; - austenitic welds. The purposes of the testing can be very different, for example: - for the assessment of quality level (manufacturing); - for the detection of specific discontinuities induced in service. Acceptance levels are not included in ISO 22825:2017, but can be applied in accordance with the scope of the testing (see 4.1). This document is applicable to both manual and mechanized testing.
