Freight Wagon Wheel Inspection During Reprofiling

Surface cracks on freight wagon wheels can compromise operational safety. Eddy current testing enables reliable inline inspection during reprofiling without additional handling.

The challenge

Freight wagon wheels are exposed to high mechanical loads, rolling contact fatigue and thermal stress during braking. Over time, these influences can cause surface cracks and wear that compromise operational safety and reduce wheel lifetime.

Conventional inspection methods such as magnetic particle testing (MT) require several manual handling steps and interrupt the maintenance process. A faster inspection method is needed to reliably detect surface defects while minimizing downtime and preserving wheel material.

The solution

FOERSTER's TCM integrates eddy current testing directly into the wheel reprofiling process, enabling reliable inspection without removing the wheel from the machine.

Using ECA technology and a wheel-adapted array probe, the system detects surface and near-surface cracks in real time. Defects are visualized immediately, allowing maintenance personnel to assess defect depth and determine the minimum material removal required.

The TCM supports efficient wheel inspection through:

Inline crack detection during reprofiling
High-resolution Eddy Current Array (ECA) inspection
Real-time defect visualization and evaluation
Reliable inspection without consumables

The result

Integrating eddy current testing into the reprofiling process significantly reduces handling time and shortens inspection cycles while eliminating the need for separate inspection steps.

Reliable defect detection supports predictive maintenance, minimizes unnecessary material removal and extends wheel service life. The combination of inline inspection, objective evaluation and reduced downtime improves maintenance efficiency while contributing to safe and reliable railway operation.
