ISO 22825:2017规定了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； -镍基合金焊缝； -双相钢焊缝； -异种金属焊缝； -奥氏体焊缝。 测试的目的可能非常不同，例如: -用于评估质量水平（制造）； -用于检测运行中产生的特定不连续性。 ISO 22825:2017不包括验收水平，但可根据测试范围应用（见4.1）。 ISO 22825:2017的要求适用于手动和机械化测试。

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.
