X-Ray online detection is a non-contact detection technology that can be used to detect defects, cracks, deformations, and other issues on the surface of materials such as metals, plastics, and glass. It can perform non-destructive testing on products without opening the box, detecting defects, foreign objects, and other issues, greatly improving the quality and safety of the product.

The basic principle of X-ray online detection is to use phenomena such as absorption and scattering of X-rays through materials to image and detect samples. X-rays are high-energy electromagnetic waves with strong penetrating power, which can penetrate various substances. Therefore, they can be used to detect products of different materials and forms. When conducting X-ray online testing, specialized testing equipment is required. These devices include X-ray generators, detection probes, imaging sensors, etc. During the detection process, after the X-ray passes through the sample, the sensor will image it and convert it into a digital signal, which is then processed using a specific algorithm for image processing. By analyzing and comparing these images, possible foreign objects, defects, and other issues in the sample can be detected.

The testing method for X-ray online detection usually includes the following steps:

Material preparation: Firstly, the material to be tested needs to be placed on the testing platform and compared with the standard sample.

Set testing conditions: According to the type of material and testing purpose to be tested, set testing conditions such as X-ray dose, focal size, detector position, etc.

Test: After setting the test conditions, start the X-ray generator, expose the materials to X-ray, and the receiving detector will record the attenuation of X-ray.

Analysis results: By analyzing the data recorded by the detector, it is possible to identify internal defects and problems in the material, such as cracks, voids, deformation, etc.

When testing X-Ray online detection, the following aspects need to be noted:

Environmental testing: Because X-rays have certain hazards, environmental testing is required before testing to ensure that the radiation value in the testing area does not exceed national standards.

Equipment testing: Check the operational status and performance of the testing equipment, including X-ray generators, sensors, imaging transmission systems, etc.

Sample preparation: Prepare the sample, such as packaging, removing foreign objects, etc., to ensure the integrity and accuracy of the sample.

Data analysis: Analyze the detected data to verify the accuracy and reliability of the detection results.

In practical applications, the test results of X-Ray online testing usually require comparing the data of standard samples with the data of the testing platform to determine whether there are defects or problems. At the same time, in order to improve the accuracy and precision of detection, it is necessary to conduct statistical analysis and processing of test data to eliminate testing errors and deviations.
