New brooms sweep clean – innovative nondestructive testing en route to standardization

09.10.2014

Nondestructive tests find defects that remain hidden to the naked eye, for example, defective weld connections, cracks in the material, voids or inclusions. Fraunhofer IZFP is currently preparing standardization of inductively excited thermography, a novel nondestructive inspection method. This procedure is to be configured as a replacement for magnetic particle testing.

The industrial demand for manufacturing-accompanying nondestructive inspection by standardized methods has grown steadily in recent years. Compared to established standardized procedures novel approaches of nondestructive testing methods offer tremendous progress and improvements such as shorter testing times, high automation, reduced equipment and training costs, lower susceptibility to operating error, among other things.

Nevertheless, their comprehensive industrial spread is hindered by a lack of standards and standardization. So often the user cannot provide proof of test equipment aptitude of the procedure for the specific problem because of high costs, lack of resources and/or lack of interdisciplinary methodological skills.

In particular, SMEs as suppliers are facing reasoning difficulties for warranting the use of non-standard test methods or even expose themselves to a high degree of financial risk. Thus, existing potential savings in time and expense while improving quality cannot be exploited, whereby the position of German SMEs in the global economic system is weakened.

Inductively excited thermography is a not yet standardized but already widespread alternative to traditional magnetic particle testing (MT). The test method is ideal for fully automatic semifinished goods inspection of metallic parts and components.

Unlike MT, inductive thermography provides the evaluation of the defect depth. Moreover, in most cases there is no need to remove surface coatings and the subsequent cleaning of the surface is completely eliminated. To date, also in this case a comprehensive acceptance is, however, obstructed by the lack of standardization.

In the near future, engineers of the Fraunhofer Institute for Nondestructive Testing IZFP in Saarbrücken together with industry representatives will work out specific solutions that will pave the way for standards and standardization of new inspection methods.

The general objective of this project is to strengthen the competitiveness in particular of small and medium-sized enterprises. To this, amongst others a standardization procedure for the inductive thermography is triggered, the conclusion will significantly facilitate access to this inspection technology.

Represented by the Institute for Standardization e. V. (DIN) and the German Aerospace Center (DLR) as executing agencies, the research project is funded since September 2014 to February 2016 by the Federal Ministry of Education and Research (BMBF) with more than 100,000 euros.

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...

Im Focus: Glacier bacteria’s contribution to carbon cycling

Glaciers might seem rather inhospitable environments. However, they are home to a diverse and vibrant microbial community. It’s becoming increasingly clear that they play a bigger role in the carbon cycle than previously thought.

A new study, now published in the journal Nature Geoscience, shows how microbial communities in melting glaciers contribute to the Earth’s carbon cycle, a...
