Non-destructive testing (NDT) plays an essential role in safety-critical industries such as aviation, automotive engineering, power generation, mechanical engineering and medical technology. It makes it possible to detect material and manufacturing defects without damaging components. A particularly well-established method is fluorescent penetrant testing, which makes the finest surface defects visible. The quality and effectiveness of this process depends heavily on the UV light source used, among other factors.

At MR Chemie, we offer numerous alternatives with our wide range of product families for many applications, whether colored or fluorescent.

MR Chemie GmbH’s Reflecon 3D scanning sprays are key tools for achieving precise and detailed scanning results at high speed.

Many users of penetrant and magnetic particle testing techniques use various tools daily to carry out their work safely and in accordance with standards. However, there are also a few inspectors who are either unaware of their existence or how they work. In this article, we would like to provide you with a brief overview of the most used tools.

The main criterion for deciding to use a background color is usually insufficient contrast formation between the workpiece surface to be tested and the magnetic particles in the test equipment used. However, as is often the case in NDT, it is precisely these contrasts that enable us to reliably evaluate our tests. So what else is there to say about contrast paint? Quite a lot!

The Reflecon TopoTrack 2in1 scanning spray was developed to significantly minimise the process time of a 3D scan. The process time is not only reduced by eliminating the need to stick on and remove reference points, but also because you can guide your scanner over the object much faster.

There are many aspects such as storage, handling (including transportation if necessary), but also the disposal of test equipment. Safety data sheets must also first be understood in order to ensure safe handling of test equipment. Ideally, it is better tob e safe than sorry.

Our pocket-sized penetrant system is the ideal solution when only small areas need to be inspected, the environment does not allow for contamination or known areas need to be inspected quickly.

The inspection with a hand magnet, especially in fluorescent crack testing, often presents a challenge to operational processes due to resulting waiting times in production. Additionally, the operation of the three essential components – hand magnet, testing material, and UV light – usually requires two hands constantly switching.

The ideal application is a homogeneous matting layer and a compromise between various requirements: Necessary layer thickness, necessary sublimation time, measurement uncertainty of the scanner and software.
