NDT (Non-destructive testing),就是利用声、光、磁和电等特性,在不损害或不影响被检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,给出缺陷的大小、位置、性质和数量等信息,进而判定被检对象所处技术状态(如合格与否、剩余寿命等)的所有技术手段的总称。从...
Nondestructive testing (NDT) is the process of inspecting, testing, or evaluating materials, components or assemblies for discontinuities, or differences in characteristics without destroying the serviceability of the part or system. In other words, when the inspection or test is completed the part can...
What is Laser Shearography?激光错位散斑干涉是一种用于无损检测(NDT)和质量控制的光学测量技术,通常用于复合材料和金属材料。该方法用于缺陷的快速检测。 激光错位散斑干涉原理包括在中性状态和加载状态下对测试对象进行干涉比较。先进的软件算法执行实时图像处理,以识别这两种状态之间的平面外变形的变化,从而在一定的负载...
Non-destructive testing (NDT) is a testing and analysis technique used by industry to evaluate the properties of a material, component, structure or system for characteristic differences or welding defects and discontinuities without causing damage to the original part....
Non-Destructive Testing (NDT):Using methods like X-ray or ultrasonic testing to detect internal defects without damaging the weld. Destructive Testing:Cutting and testing a sample of the weld to verify its mechanical properties. 4) Finishing ...
The main application of a C-scan or XRD scan in an NDT process is to analyze cracks that are not visible to the naked eye. It finds cracks on welds and can also locate them inside components such as engine blocks, cylinder heads, valves, etc. ...

An example of a magneto-resistance sensor is the Crocus Technology CT452. This sensor implements TMR, a new type of magneto-resistance technology. TMR sensors have a fixed magnetic reference layer, an insulator, and a magnetic sensing layer that follows the external field. 技术探讨 发布时间 ...
CR technology in three steps Instead of film, an imaging plate is exposed to X-ray or gamma radiation. The imaging plate is digitized by the scanner and then erased for immediate reuse. The digital image is then displayed on a computer monitor for evaluation with specialized software. ...
