Abstract
Additive technologies, namely selective laser melting (SLM), are often used in manufacturing products of critical duty. At the same time, the SLM process may be accompanied by the appearance of specific defects in the product. We present the results of radiation monitoring of aviation blanks manufactures using additive technology by digital radiography. A digital detector system was used as an X-ray converter. It is shown that the methods of film radiography traditionally used for control in the case of aircraft objects are not always effective. The method of digital radiography, on the contrary, is the most adequate. Comparison of the results of digital radiography with data of traditional radiography revealed that the time spent on radiation monitoring when using an automated manipulator is significantly reduced, while the monitoring performance increases dramatically. The results obtained can be used to improve the methods of radiation monitoring of aircraft objects manufactured using additive technologies.
