Explore our industry-leading portfolio of nondestructive testing instruments to ensure safety and efficiency for axles, wheels and tracks.
Advanced NDT technologies for Rail
The rail industry demands unwavering safety and operational efficiency. From the integrity of axles and wheels to the condition of the railway tracks themselves, every component plays a critical role in ensuring smooth, reliable, and safe transportation.
Waygate Technologies, a Baker Hughes business, understands these demands and offers a comprehensive portfolio of nondestructive testing (NDT) solutions based on our Krautkrämer legacy, specifically designed to meet the unique challenges of the rail industry. Our advanced NDT technologies empower you to proactively identify potential defects, prevent costly failures, and optimize maintenance schedules.
By leveraging our cutting-edge solutions, you can:
Enhance Safety:
Detect critical flaws before they compromise structural integrity, minimizing the risk of accidents and ensuring passenger and freight safety.
Improve Efficiency:
Optimize maintenance programs by focusing on areas requiring attention, reducing downtime and maximizing asset utilization.
Reduce Costs:
Extend the life of critical components and prevent serious failures, resulting in significant long-term cost savings.
Ensure Compliance:
Meet stringent industry regulations and maintain the highest standards of quality and safety.
Railway axles are subject to significant stress and fatigue during operation. Early detection of defects is crucial for preventing failures and ensuring operational safety.
Our solutions:
- Krautkrämer Solid Axle Manual Tester - Front-face ultrasonic inspection of solid rail axles
- Krautkrämer Hollow Axle Probe System - Detection of transverse cracks in hollow axle wheelsets
Railway wheels are critical safety components subjected to extreme mechanical stress, and continuous wear during operation. Components must withstand enormous loads while maintaining precise geometry for smooth and safe railway operations. Therefore, regular and accurate inspection of wheels is essential to detect surface and subsurface defects, fatigue cracks, and wear patterns before they lead to operational failures or derailments.
Our wheel inspection solutions combine portable and automated ultrasonic testing systems to enable comprehensive detection of both surface and volumetric defects, ensuring maximum safety while optimizing maintenance intervals and operational efficiency.
Our solutions:
- Krautkrämer Wheelstar UFPE - Fast inspection of wheelsets
- Krautkrämer Wheelstar RPS - Robotic inspection of dismantled train wheels
- Krautkrämer RotoArray ComPAct - Flexible inspection of composite parts such as train car bodies
Track integrity is fundamental to safe and efficient rail operations. Railway tracks are safety critical components for rail operation. Heavier loads, higher speeds, and more rail operations require regular track inspections to ensure their integrity. Our track inspection solutions provide early detection of defects to prevent derailments and optimize maintenance schedules.
Our solutions:
- Krautkrämer SPG3 Rail Track Tester - Efficient inspection of railway tracks with trolley
- Krautkrämer USM 100 - Ergonomic, portable flaw detection with unrivaled ease of use
FAQs
Ultrasonic rail testing refers to a nondestructive inspection method that uses high‑frequency ultrasonic sound waves to check the internal condition of rail infrastructure (e.g., rails and wheel components) without damaging them. The technique emits ultrasonic waves into the rail material; when those waves encounter internal discontinuities such as cracks, voids, inclusions, or defects, part of the sound is reflected back to a receiver. By analyzing the reflected signals, inspectors can determine the presence, location and size of internal flaws that aren’t visible on the surface. This helps rail operators detect problems early and take corrective maintenance before failures occur.
In 1949, the Krautkrämer brothers introduced Germany’s first ultrasonic testing device capable of visualizing internal flaws in steel, marking a turning point in industrial inspection technology. Learn more about Waygate Technologies' Krautkrämer legacy here.
Rail transport is at the heart of sustainable mobility. It is fast, safe, and energy efficient, making it a cornerstone of global efforts to reduce carbon emissions while keeping people and goods moving. But with rising demands for higher capacity and speed, maintenance facilities face mounting pressure: trains must stay operational with minimal downtime, and safety cannot be compromised.
