ActiveNon-destructive testing—Testing method for large diameter round bars by focused ultrasound
无损检测 大直径圆棒聚焦超声检测方法
Application Summary AI generated
This standard specifies a focused ultrasonic testing method for detecting internal defects such as cracks, inclusions, and porosity in large diameter round bars. It is primarily applied in the metallurgical and heavy machinery industries for quality control of forged or rolled bars with diameters typically exceeding 100 mm, ensuring material integrity before further processing or use in critical components like shafts and rotors.
