ActiveNon-destructive testing of welds—Ultrasonic testing—Use of time-of-flight diffraction technique (TOFD)
焊缝无损检测 超声检测 衍射时差技术（TOFD）的应用
Application Summary AI generated
This standard specifies the methodology for applying the Time-of-Flight Diffraction (TOFD) ultrasonic technique to detect and size discontinuities in welded joints. It is primarily used in manufacturing and construction industries for the non-destructive testing of steel weldments, such as in pressure vessels, pipelines, and structural steelwork. The standard provides technical requirements for equipment, calibration, and evaluation procedures to ensure accurate flaw detection and sizing in production and in-service inspection contexts.
