The X-ray transmission inspection can provide a picture of whether there are defects in the inspection site of the casting and the relevant size, and the X-ray inspection system is widely used in industrial production.

X-ray digital radiography and industrial computed tomography are two important technical branches in the field of industrial nondestructive testing. DR Detection technology is a kind of real-time X-ray digital imaging technology. The advantages are strong real-time, can be online real-time detection of workpiece structure media discontinuity, structural form and other quality defects, in the field of rapid non-destructive testing has broad prospects for development.

Industrial CT is regarded as a major technological breakthrough in the field of nondestructive testing technology. The application of industrial CT technology in parameter analysis and failure study has affected almost all industrial fields.

In non-destructive testing, the need for X-ray technology is more extensive. Among them, X-ray technology includes two directions: radioisotopes and X-rays. X-ray is currently the mainstream application technology direction. Compared with ultrasonic, infrared, electromagnetic and other technologies, X-ray penetration is stronger and can be applied in a wider range of fields.
