X-ray based wheel inspection


X-ray based inspection is the standard inspection method for aluminum wheel inspection.

The majority of wheels produced are meanwhile made of aluminum, on the one hand to reduce vehicle weight, but also due to the look they create. Due to fluctuations in the casting process of wheels, material defects such as blowholes and porosities cannot be completely ruled out, not even using the most modern production methods available. The wheels' stress tolerance can be impaired thereby. A safety risk can arise as a result. X-ray inspection makes material defects in wheels visible. That is why radioscopy X-ray systems have been deployed successfully for decades in spot-check sample inspection during wheel production, and especially for 100% wheel inspection. YXLON offers manual and fully automated wheel inspection systems for all throughput requirements, as well as for wheel inspection before or after mechanical processing and lacquering.

Computed Tomography goes yet another step further in wheel inspection because it also enables wheels to be depicted as three-dimensional objects, thus permitting an exact evaluation of defective areas' position, size and frequency. Casting defects in wheels can be detected with the help of virtual cross-sections using the materials' different densities. Respective microporosities in are not always able to be found clearly when alternate wheel inspection methods are used. Their quantitative determination of defects requires samples obtained by grinding the material(s): such methods are time-consuming and have a destructive effect on the wheel.
CT measurement replaces this cost-intensive procedure of destructive wheel inspection. A definitive statement regarding potential material defects in the wheel can be generated within a few minutes. This time saving comes especially to bear during an ongoing wheel casting process and in the case of initial production runs for new types of wheels. And when defect analysis occurs on an automated basis, regions and tolerances for the respective size of those porosities to be detected can be stipulated within the analysis software. YXLON offers a variety of CT solutions for this sector of wheel inspection.
