- Scope
- This standard specifies the low ultrasonic attenuation (especially small scattering attenuation) metal material fusion welding welding joint manual ultrasonic testing technology with a base metal thickness of not less than 8 mm. The temperature of the weld and its base metal is between 0 and 60 °C during the test. This standard is mainly applied to full penetration welds where both the base metal and the weld are ferritic steel. This standard specifies the ultrasonic value depending on the material, which is based on the steel with a sound velocity of longitudinal wave of (5920±50) m/s and a sound speed of transverse wave of (3255±30) m/s. This standard specifies four detection levels. Different detection levels correspond to different defect detection rates. Appendix A gives guidance on the selection of test levels A, B and C. This standard specifies general requirements for the use of detection class D only in special applications. Detection class D can only be used when specified in the specification. Special applications include non-ferritic weld inspection, partial penetration weld inspection, weld inspection using automated equipment, and weld inspection at temperatures outside the 0-60°C range. This standard can be used for display evaluation or acceptance by any of the following techniques: a) evaluation based on display length and echo amplitude; b) evaluation based on display characteristics and display size (using probe movement technology). Which technology to use should be clearly specified.
