ActiveDestructive tests on welds in metallic materials - Etchants for macroscopic and microscopic examination
金属材料焊缝破坏性试验 宏观和微观检验用侵蚀剂
Application Summary AI generated
This standard specifies the types, compositions, and preparation methods of etchants used for macroscopic and microscopic examination of welds in metallic materials. It is applied in the manufacturing and quality control of welded structures, particularly in industries such as automotive, aerospace, and pressure vessel production, where inspectors use these etchants to reveal weld microstructure and detect defects like cracks or porosity. The standard ensures consistent and reliable etching procedures for destructive testing of weld joints.
