Whether it's fallen concrete pylons caused by corroded tension wires, a new motor due to damaged pistons or defective sheet steel, even the tiniest cracks or smallest traces of corrosion can have serious consequences, especially in safety-critical environments.
With magnetic stray flux inspections, these flaws can be quickly visualized without destroying or contaminating the material.
As an alternative to magnetic powder tests, this method can also be used wherever the magnetic powder approach is unsuitable.
Engineers at Saarbrucken-based Fraunhofer IZFP will be introducing a mobile handheld device for magnetic stray flux testing at the 29th annual CONTROL trade fair in Stuttgart (hall 1, exhibit booth 1502), which runs May 5 to May 8.
Scientists at the Fraunhofer Institute for Nondestructive Testing IZFP in Saarbrucken have developed a handheld, wireless test device called FLUXI which is based on magnetic stray flux technology.
This method relies on the same physical effect exploited by magnetic powder testing, a standard and widely-used inspection process in steel manufacturing.
When an external magnetic field is applied to sharp-edged cracks on the surface of a component, additional magnetic dipoles form, which then induce magnetic leakage near the surface. This stray field can be detected and processed with magnetic field sensors.
The enormous potential for instrument technology miniaturization provides a key advantage since extremely difficult to access areas of the component can be quickly and easily subjected to magnetic stray flux inspections.
With FLUXI, manufactured parts and components can be rapidly scanned, allowing potential surface defects to be displayed as images.

The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.
Vehicles already offer diverse communication interfaces and more and more automated functions, such as distance and lane-keeping assist systems. At the same...
A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.
The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...
At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.
At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
