AbolishedSteel forgings - Method for ultrasonic testing
钢锻件超声检测方法
Application Summary AI generated
This standard specifies the ultrasonic testing method for steel forgings, including equipment requirements, calibration procedures, and defect evaluation criteria. It is applied in the metallurgical and heavy machinery industries for quality control of forged components such as shafts, rotors, and discs used in power generation, aerospace, and pressure vessel manufacturing. The method is used to detect internal discontinuities like cracks, inclusions, and porosity during production or in-service inspection.
