![]() Think of a crack in a brake disc: there is a chance that after a certain period of operation the brake disc severely tears while decelerating. In the worst scenario, this can lead to component failure. This is because even the smallest cracks, which initially do not pose a problem, can become enlarged and widen under permanent load. Eddy current testing is usually used here. The most common types of defects to be found in a surface inspection are:Ĭlassical component defects are cracks spotted in the material surface. For instance, decisive influencing factors are the application area of the component, the material that is made of, and its dimensions. The defects catalog from customers is diverse. What sort of defects can be found in components? These ensure a continuous and in-depth inspection of safety-relevant components during the manufacturing process and before installation. If the pipelines of a building fail, considerable water damage can follow with subsequent high renovation costs.Īccordingly, standards in the automotive sector and many other industries are defined. If, for example, a roller coaster breaks apart while operating, human lives are immediately endangered. There are many safety-critical applications or major economic consequential damages where components fail or do not meet their requirements. Why is non-destructive material testing necessary? Far more extensive tests are therefore essential to prove the corresponding properties over the service life. This is attributed to the fact that a higher demand is being increasingly placed on testing the components in parallel with continuous operation. At the same time, in many industries it is no longer sufficient to test only the geometric dimension of a component. Due to its efficient performance, this inspection procedure has become crucial for comprehensive process control. Non-destructive material testing has become firmly established in process monitoring in recent years. ![]()
