Abstract
In the field of railroad safety, effective detection of surface cracks is critical, necessitating reliable, high-speed non-destructive testing (NDT) methods. This study introduces a hybrid Eddy Current Testing (ECT) probe, specifically engineered for railroad inspection, to address the common issue of 'lift-off noise' due to varying distances between the probe and test material. Unlike traditional ECT methods, this probe integrates transmit and differential receiver coils, aiming to enhance detection sensitivity and minimize lift-off impact. The research involves optimizing the ECT probe through various driver coils, focusing on three key aspects: a) explains methodology of real-time data processing algorithm; b) probing the frequency range near the receiver coil's electrical resonance, c) assessing sensitivity changes across different lift-off distances. The experimental outcomes indicate that the newly designed probe with figure 8-shape driver coil significantly improves sensitivity in detecting surface cracks on railroads. It achieves an impressive signal-to-noise ratio (SNR) exceeding 60 for defects with minimal dimensions of 0.8 mm in width and depth. This study represents a notable advancement in NDT techniques, with profound implications for enhancing railroad safety by improving crack detection efficiency.
