Local Expertise: Your Trusted Partners for Quick Instrument Solutions

Checking of boards in our laboratory

With locations in Germany, Switzerland and the United States, we offer comprehensive manufacturer support to ensure you receive first-class assistance directly on-site. In addition, our extensive global network of experienced partners ensures that you can find the first point of contact for first-level support in your country for fast assistance. Our partner companies usually keep a selection of devices, sensors and cables in stock as a reserve, which further increases the reliability of your NDT activities.

In many cases, our partners can quickly get your instrument back to work by module replacement or simple repair. For more complex issues, the instrument needs to be shipped to our main service facility in Germany for evaluation and repair. In the meantime, we can provide you with a replacement device so that your production line can continue undisturbed.

Expert Technical Support: Swift Solutions for Your Challenges

Frequently, however, some problems can also be solved in direct contact. You can count on the support of our experts from all disciplines even from abroad by email and/or phone. Facing technical challenges? Don't hesitate to reach out to our experts. Whether it's a simple query or a complex issue, our team is here to assist you. Contact us today for swift solutions.

Crack and Grinder Burn Detection

Parts with defined defect areas of varying intensity are required to assess the eddy current method's ability to detect defects in components and later monitor testing sensitivity in an industrial setting. Artificial Defects (also known as Reference Defects or EDM Defects) must be defined and reproducibly produced in terms of size, position, and type. Moreover, they should ideally produce similar physical testing effects to real damage. It is not necessary, nor would it be fruitful, to attempt to create artificial defects that perfectly mimic all aspects of real damage. Sorting thresholds for identifying good and bad parts are still determined during the testing of actual parts (process validation). Parts with varying signals are selected and evaluated using reference methods. Intolerable conditions can be defined, and sorting thresholds can be determined based on component characteristics.

Master Parts for Enhanced Eddy Current Testing Sensitivity

Artificial defects are employed to set up the testing equipment before testing real parts, particularly to establish the required testing sensitivity. Master parts (reference standards) should periodically undergo the testing process to ensure that testing is conducted under consistent, reproducible conditions. This assumes that the master part remains unaffected by time-dependent changes that might alter the artificial defect.

Notches and dimples with defined depths, as per your requirements, are created in your test parts through electrical discharge machining (EDM) to verify the sensitivity of crack detection. If your customer desires it, the master parts can be measured in an accredited laboratory, and you will receive the parts along with a certificate. Master parts that undergo regular testing are naturally subject to wear. We offer the option of chromium plating for the master parts to extend their lifespan without affecting the eddy current results.

Precision Testing Solutions: Laser-Generated Grinder Burn References

Defined grinder burn damage on components serves as reference standards for eddy current testing and also for verification of a nital etching process. After a preliminary examination, the appropriate process parameters for producing laser artificial defects on your components are determined. Subsequently, the defined grinder burn structure is created with one mark (dot, stroke, or area) on two identical parts. Finally, a metallographic cut is performed on one of the two parts to evaluate the microstructure as a control measure of success. The master part is additionally tested for its eddy current signals before being dispatched to you. Upon request, an X-ray diffraction analysis can be performed to determine residual stress on the surface of the defect. We collaborate closely with partner laboratories on this complex matter and have successfully met each customer's requirements thus far. Please contact us – we eagerly await your exciting projects.

By the way, chromium plating for grinder burn masters is not feasible, as it could falsify the eddy current signal for this type of defect. We recommend lacquering to protect against external factors such as rust.
