| Abstract: | Through the analysis and comparison among radiographic testing standards at home and abroad, such as DL/T 821--2002, the technical regulations of radiographic examination of butt welded-joints of pressure steels pipes and tubes, and ASME boiler and pressure vessel and so on, combining with the theory and practical operating, suggestions about how to determine round pore defects was proposed. |
