At present, X-ray digital imaging detection technology has been widely used in aviation, aerospace, petroleum, chemical, Automotive, railway, electric power, machinery, pressure equipment and other industries weld quality testing. In the foundry industry, X-ray digital imaging inspection technology has become an essential test for the internal quality inspection of nonferrous metal castings and steel castings One of the means of measurement. With the development of automotive industry, X-ray digital imaging technology has good application prospects in automotive aluminum-magnesium alloy castings. With the development of large equipment manufacturing industry, X-ray digital imaging technology has good application prospect in the steel casting equipment. In the field of non-metallic materials, composite materials, for ceramic materials, honeycomb structural products, rubber products, resin-based molded products Department of quality testing, from a multi-angle product testing, is conducive to inclusion, cracks, delamination and structural defects detection and analysis. X-ray digital imaging detection technology can be used for pipe inspection with outer protective layer; Detection, transportation fluid pipe wall corrosion testing. Ammunition filling, cannonball fuses, high voltage switch contacts and other important devices assembly accuracy and structural integrity testing, is X-ray Digital imaging technology, an important application areas. Devices represented by micro-focus X-ray digital imaging systems are also widely used in the microelectronics industry. With the development of X-ray digital imaging technology, X-ray digital imaging technology has been widely used in logistics testing, mineral screening and cultural relics, archeology Other fields have good application prospects. Non-destructive testing X-ray digital imaging detection guidelines1 ScopeThis standard specifies the X-ray digital imaging detection of technical features, testing equipment, characterization, image resolution, image noise, image Contrast, image quality, technical application and other basic requirements. This standard applies to metal materials, non-metallic materials, composite materials and other products X-ray digital imaging detection guidance.2 Normative referencesThe following documents for the application of this document is essential.
