X-ray-based nondestructive testing system for industrial component defects and its testing method

Abstract

The invention discloses a nondestructive testing system for industrial part flaws based on X rays. The nondestructive testing system comprises X-ray imaging equipment, an image enhancing part, an image acquisition card and an image work station, wherein the X-ray imaging equipment is used for receiving the X rays penetrating through an industrial part to be detected; the X-ray imaging equipment is provided with a signal detection part and an imaging part, which are connected with each other; the image enhancing part is used for receiving an original image signal generated by the X-ray imaging equipment in real time and carrying out signal enhancing processing on the original image signal to obtain an enhanced image signal; the image acquisition card is connected with the image enhancing part; and the image work station is provided with a buffering part and a flaw identification part, which are connected with each other, and the image acquisition card is used for transmitting the enhanced image signal acquired by the image acquisition card to the buffering part. With the adoption of the nondestructive testing system, the technical problems in the prior art that the flaw detection efficiency is low, the repeatability is poor and mistakes are extremely easily made are solved.

Description

technical field [0001] The invention relates to the technical field of industrial product inspection, in particular to an X-ray-based nondestructive inspection system for industrial component defects and a detection method thereof. Background technique [0002] Radiographic testing is one of the important methods of conventional non-destructive testing. It is widely used in aviation, aerospace, nuclear power, national defense and other industrial sectors, and plays an important role in industrial production and national economy. At present, in actual production, film photography is generally used for radiographic inspection. The imaging quality of X-ray film photography is high, and it can correctly provide reliable information on the real defect of the tested piece. However, it has the disadvantages of complicated operation process, high operating cost, difficult to save the results, inconvenient query and portability, and vulnerable eyes of reviewers. Disadvantages such a...
