Find defects that cannot be seen from the outside.

Wheel and axle geometry can look correct while the material contains an internal defect. Actemium NDS is the route when the question is material integrity, not just dimensions.

In practice: inspect inside the wheel or axle without cutting it apart.

Inspect the rim of an installed railway wheel for internal defects.

Best for: depot wheel-rim inspection without wheelset removal

Inspect hollow axles from the inside using a controlled ultrasonic route.

Best for: fleets using hollow-axle designs

Combine ultrasonic, phased-array and surface inspection around a removed wheelset.

Best for: heavy overhaul, manufacturing and centralized wheelset shops

Bring a compact inspection system to the maintenance location.

Best for: distributed depots and field work

Use feasibility studies, simulation, onsite inspection and Level III support.

Best for: new components, difficult geometries and method qualification

Wheel rim, solid axle, hollow axle or full wheelset.

Match the physics to the defect location and geometry.

Collect and localize relevant indications.

Continue, investigate further or remove the component from service.

Wheel gauges and profile systems tell you shape and wear. NDT addresses what may be happening inside the metal. One cannot substitute for the other.

Before: the component looks acceptable from the outside.

After: its internal condition has been inspected using a defined method.

CBP translates the maintenance problem into the inspection scope, coordinates Actemium engineering, and can structure equipment, commissioning, training or inspection-service support.
