标准摘要
[中文适用范围]： 本文件规定了在制定以下焊缝超声波检测程序时应遵循的方法： ——不锈钢焊缝； ——镍基合金的焊缝； ——双相钢的焊缝； ——异种金属焊缝； ——奥氏体焊缝。 测试的目的可能有很大不同，例如： ——评估质量水平（制造）； ——用于检测使用中引起的特定不连续性。 验收级别不包含在本文件中，但可以根据测试范围应用（见 4.1）。 本文件的要求适用于手动和机械化测试。 [外文原描述]： ISO 22825:2017 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). The requirements of ISO 22825:2017 are applicable to both manual and mechanized testing.
