AbolishedNondestructive testing symbols for welds
焊缝无损检测符号
Application Summary AI generated
This standard specifies the graphical symbols and notation used to indicate nondestructive testing (NDT) methods for welds on engineering drawings. It is applied in manufacturing and construction industries to unambiguously communicate testing requirements, such as radiographic or ultrasonic inspection, for welded joints. The standard ensures consistent interpretation of NDT instructions across design, fabrication, and quality control processes.
