UVLED detection internal structure

    Testing the internal structure of an item has always been a problem. But the emergence of uvled has made a major breakthrough in this field. In the non-destructive detection of the internal structure of the article, the use of uvled endoscopes is more advanced than the previous technology.

UVLED non-destructive testing technology utilizes the phenomenon that certain physical properties of a substance change its physical quantity due to defects or structural differences, and can be understood by measuring these changes without damaging the performance and morphology of the test object. And a special detection technique for evaluating the nature, state, quality or internal structure of the materials, products and equipment components being tested. At present, UVLED electronic video endoscopes using UVLED light source technology, UVLED can be said to fundamentally change the practical performance of industrial video endoscope products, which is of great significance for non-destructive testing technology.

As a new type of non-destructive testing instrument, UVLED non-destructive testing adopts imported high-definition CCD to ensure the clear and realistic video endoscope image. The UVLED non-destructive testing tool is used for the detection of various defects inside the workpiece, such as cracks, inclusions, pores, etc. It is the main positioning that cannot be observed by the naked eye. In many environments and conditions, professional visual portable non-destructive internal structure testing tools are needed.

UVLED non-destructive inspection visual inspection range: weld surface defect inspection. Check the weld quality such as weld surface cracks, incomplete penetration and weld leakage. Internal cavity inspection. Check for surface cracks, peeling, pulling, scratches, pits, bumps, spots, corrosion and other defects. Status check. When certain products work, endoscopic testing is performed according to the items specified in the technical requirements. Assembly inspection. When required and required, use industrial video endoscopes to check the assembly quality; after assembly or a certain process is completed, check whether the assembly position of each component meets the requirements of drawings or technical conditions; whether there are assembly defects. Excess inspection. Check for residual internal debris, foreign objects, etc. in the inner cavity of the product.

UVLED non-destructive testing is to detect the presence or absence of defects or inhomogeneities in the object under test without impairing or affecting the performance of the object being tested, giving information such as the size, location, nature and quantity of the defect.

Compared with destructive testing, the advantage of UVLED non-destructive testing is non-destructive, because UVLED non-destructive testing does not damage the performance of the tested object when it is tested; it is comprehensive, because the detection is non-destructive, so if necessary 100% comprehensive inspection of the tested object; full-scale, destructive testing is generally only suitable for testing raw materials, such as stretching, compression, bending, etc. commonly used in mechanical engineering, destructive testing is for manufacturing Raw materials, for finished products and supplies, unless it is not ready to continue to serve, otherwise it is impossible to carry out destructive testing, and non-destructive testing does not damage the performance of the object being tested. Therefore, it can not only test the raw materials for manufacturing, the intermediate process links, and the final finished products, but also the equipment in service.

The biggest advantage of Uvled non-destructive testing is that it can maintain zero damage to the detected items. This is not possible with previous detection methods. This high-tech is destined to be widely adopted. And quickly promoted in the market.
