Actemium NDS spans installed-wheel inspection, hollow-axle inspection, automated wheelset inspection, mobile systems and NDT engineering services.
Portable ultrasonic wheel-rim inspection while the wheelset remains installed on the vehicle. It is designed for the question: can we inspect the wheel internally without first removing the wheelset?
EXPLORE RELATED SOLUTIONMechanized ultrasonic inspection of hollow axles from the bore. This is a different geometry and inspection problem from wheel-rim testing.
Stationary systems combine ultrasonic, phased-array and surface inspection around a removed wheelset for controlled heavy-overhaul or production workflows.
Portable inspection systems plus CIVA simulation, feasibility studies, custom probes, onsite inspection and Level III support for components that do not fit a standard route.
Reduce unnecessary disassembly when the required defect coverage can be achieved on the installed wheel.
VIEW SOLUTION →Use a method designed around solid or hollow axle geometry rather than reusing a wheel procedure.
Integrate multiple NDT methods into a repeatable wheelset-shop station.
Use simulation, feasibility and expert support when geometry or acceptance criteria are unusual.
The selector narrows the architecture. The final method still depends on component geometry, reference defects, coverage and acceptance procedure.
Start with the installed-wheel ultrasonic architecture when wheel-rim integrity must be checked without removing the wheelset.
Wheel diameter, flange and profile tools tell you shape. Actemium NDS addresses defects inside or near the surface of the metal. A dimensionally correct wheel can still require NDT.
| Question | Dimensional metrology | Actemium NDT |
|---|---|---|
| What is being checked? | Shape, size, wear | Internal / near-surface integrity |
| Typical output | Dimension or profile | Indication / defect response |
| Can one replace the other? | No | No |
| Selection basis | Drawing / tolerance | Defect type, material, geometry, coverage, procedure |
CBP records show participation in a 2026 PT KAI procurement for three ultrasonic-testing wheelset and axle systems. This is tender/procurement evidence, not a completed deployment, and the page does not present it as one.
