标准编号：ISO 22825:2017

中文名称：焊接点的无损测试 超声测试 奥氏体钢和镍基合金中焊接点的检测

英文名称：Non-destructive testing of welds — Ultrasonic testing — Testing of welds in austenitic steels and nickel-based alloys

发布日期：2017-09

标准范围

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 this document, but can be applied in accordance with the scope of the testing (see 4.1).
The requirements of this document are applicable to both manual and mechanized testing.
