Detecting the internal structure of an object has always been a difficult problem. But the emergence of UVLED has made a major breakthrough in this area. In the nondestructive detection of the internal structure of the articles, the use of UVLED is more advanced than that of the prior art.

UVLED无损检测技术是利用物质的某些物理性质因存在缺陷或组织结构上的差异使其物理量发生变化这一现象，在不损伤被检物使用性能及形态的前提下，通过测量这些变化来了解和评价被检测的材料、产品和设备构件的性质、状态、质量或内部结构等的一种特殊的检测技术。就目前来看，采用UVLED光源技术的UVLED电子视频内窥镜， UVLED可以说从根本上改变了工业视频内窥镜产品的实用表现，对于无损检测技术意义重大。

UVLED nondestructive testing technology is a substance use some physical properties due to the presence of tissue defects or structural differences make the physical quantity to change this phenomenon, in no damage was detected using properties and morphology of the premise, by measuring these changes to understanding and evaluation of the tested materials, products and equipment components of nature, condition, quality, or internal structure of a special detection technology. At present, the UVLED light source technology using UVLED electronic video endoscope, UVLED can be said to fundamentally change the practical performance of the industrial video endoscopic products, for nondestructive testing technology is of great significance.

UVLED无损检测作为新型无损检测仪器，采用进口高清CCD，保证了视频内窥镜影像的清晰、逼真。UVLED无损检测工具以用于工件内部多种缺陷，如裂纹、夹杂、气孔等的检测，是主要定位无法通过肉眼来观察，在很多环境、条件下需要专业的可视化便携式无损内部结构探伤工具。

UVLED nondestructive testing as a new non-destructive testing equipment, the use of imported HD CCD, to ensure that the video endoscopic image clear, realistic. UVLED nondestructive testing tools to be used within a variety of workpiece defects, such as the detection of cracks, inclusions, porosity, etc. is mainly localized to the naked eye to observe, under many circumstances, conditions, need professional visual portable nondestructive internal structural flaw detection tools.

UVLED无损检查目视检测范围：焊缝表面缺陷检查。检查焊缝表面裂纹、未焊透及焊漏等焊接质量。内腔检查。检查表面裂纹、起皮、拉线、划痕、凹坑、凸起、斑点、腐蚀等缺陷。状态检查。当某些产品工作后，按技术要求规定的项目进行内窥检测。装配检查。当有要求和需要时，使用工业视频内窥镜对装配质量进行检查;装配或某一工序完成后，检查各零部组件装配位置是否符合图样或技术条件的要求;是否存在装配缺陷。多余物检查。检查产品内腔残余内屑，外来物等多余物。

UVLED non destructive inspection visual inspection scope: weld surface defect inspection. Check the surface crack, weld penetration and welding quality of welding leakage etc.. Inner inspection. Check the surface crack, peeling, pull, scratches, pits and bumps, spots and corrosion. State examination. When some of the products after work for endoscope detection in accordance with the technical requirements of project. Check assembly. When the requirements and needs, use industrial video endoscope mirror to check on the quality of assembly; after the completion of the assembly or a process, check the parts assembly position meets requirements of the drawings or technical conditions; the presence of assembly defects. Remainder check. Check the product within the cavity residual crumbs, foreign matter and other.

UVLED无损检测是在不损害或不影响被检测对象使用性能的前提下，检测被检对象中是否存在缺陷或不均匀性，给出缺陷大小，位置，性质和数量等信息。

UVLED nondestructive testing is not in any damage or does not affect the detection performance under the premise of the object, whether or not the defects detected by uniformity inspection object, given the defect size, location, nature and quantity of information.

与破坏性检测相比，UVLED无损检测的优势是具有非破坏性，因为UVLED无损检测在做检测时不会损害被检测对象的使用性能;具有全面性，由于检测是非破坏性，因此必要时可对被检测对象进行100%的全面检测;具有全程性，破坏性检测一般只适用于对原材料进行检测，如机械工程中普遍采用的拉伸、压缩、弯曲等，破坏性检验都是针对制造用原材料进行的，对于产成品和在用品，除非不准备让其继续服役，否则是不能进行破坏性检测的，而无损检测因不损坏被检测对象的使用性能。所以，它不仅可对制造用原材料，各中间工艺环节、直至最终产成品进行全程检测，也可对服役中的设备进行检测。

Compared with the destructive testing, UVLED nondestructive testing has the advantage of non destruction, because UVLED nondestructive testing in the detection performance will not damage the object to be detected; which is comprehensive, because the detection is non-destructive, so when necessary for comprehensive detection of 100% objects are detected; with full damage, detection generally applies only to detect materials, such as mechanical engineering drawing, commonly used compression, bending, destructive tests are made for raw materials, the finished products and the goods, unless not ready to let it continue to serve, otherwise it is not destructive, and nondestructive testing is not damaged due to performance testing object. So, it not only can be used for manufacturing raw materials, the intermediate process and final products during the detection, can also be tested on equipment in service.

Uvled无损检测最大的优势就是可以保持对检测物品的零损伤。这是之前的检测方式所做不到的。这一高新技术注定了会被广泛采用。并在市场上得到迅速的推广。

Uvled is the biggest advantage of NDT can keep zero damage detection of goods. This detection is not given to before. This tech is destined to be widely used. And get rapid promotion in the market.
