With the booming rail transit industry, track quality and safety are directly linked to the stability of train operations and the safety of passengers.A well-known rail manufacturer in Chengdu is committed to providing high-quality rail products for urban rail transit.To ensure high-quality track production, the manufacturer has selected the Micro-View Y-series industrial endoscope for comprehensive track inspection.
Rail transit inspection needs
The rapid development of urban rail transit has placed unprecedented demands on track accuracy, stability, and safety. During the track production process, even subtle defects can be amplified by the high pressure and high-frequency impacts of long-term train operation, posing serious safety risks. For example, cracks on the track surface, internal pinholes, or weld defects can weaken the track structure, affecting the smooth operation of trains and even causing major accidents such as derailments. Therefore, the Chengdu track manufacturer urgently needed an efficient and precise inspection method that could penetrate deep into the track to detect defects that are difficult to detect with the naked eye.
VSNDT Y Series Industrial Endoscope Solution
VSNDT Y Series industrial endoscope, with its superior performance, provided the manufacturer with a perfect inspection solution.
High-Definition Imaging: The Y Series endoscope is equipped with a high-pixel image sensor, reaching up to 2 million pixels. When inspecting rails, it clearly captures every detail inside the track, even tiny cracks or pinholes, providing inspectors with accurate visual information, enabling them to precisely determine the location, size, and shape of defects.
Extreme Depth of Field: This series offers an exceptional depth of field range of 5-200mm, 10-120mm, and 50-positive infinity. Whether inspecting the rail surface or deep within complex internal structures, it ensures clear images, eliminating the need for frequent focus adjustments and significantly improving inspection efficiency.
Intelligent System: The Y Series industrial endoscope is equipped with an intelligent operating system that supports customizable text annotations. When inspectors discover rail defects, they can add annotations in real time to record key information such as defect characteristics and location. It also features a Chinese/English renaming function for convenient categorization and management of inspection data. It also allows for quick defect identification, negative film processing, and camera settings, further enhancing inspection convenience and accuracy.
Superior Wear-Resistant Insertion Tube: Crafted from a new, four-layered insertion tube made of dual tungsten alloy wire, it boasts a wear resistance 100 times greater than that of standard endoscopes. During rail inspections, it effectively withstands the scratches and impacts of the complex railroad environment, significantly enhancing the endoscope's impact, drop, and scratch resistance. It also boasts excellent waterproof performance, ensuring stable operation in a variety of harsh environments.
360-Degree Rotation: The mechanical guide function allows the probe to rotate 360 degrees in any direction, with precise control and zero lag. Inspectors can easily reach into every corner of the track for a comprehensive, comprehensive inspection, ensuring every potential defect is detected.
Actual Inspection Results
VSNDT Y-series industrial endoscope has played a significant role in actual inspection work at a well-known rail manufacturer in Chengdu.
Efficient Defect Detection: Using the Y-series endoscope, inspectors quickly discovered numerous weld defects and pinholes within the rails. For example, in a batch of newly produced rails, inspectors used the endoscope to clearly observe a weld with incomplete penetration. This information was promptly reported to the production department for rework, preventing defective rails from entering the market and ensuring rail quality and safety.
Optimizing Production Processes: Based on defect data detected by endoscopes, the manufacturer can deeply analyze weak links in the production process and optimize production processes accordingly. For example, statistical analysis of the location and type of weld defects that occurred repeatedly revealed inappropriate parameter settings for a particular welding machine. After adjusting these parameters, weld defects were significantly reduced, significantly improving production efficiency and product quality.
Reducing Inspection Costs: Traditional rail inspection methods often require partial disassembly of the rails, which is not only time-consuming and labor-intensive, but also potentially damaging. The non-destructive testing method of the Micro-View VSNDT Y-Series industrial endoscope eliminates the need to disassemble the track, significantly shortening inspection time, reducing labor costs and equipment wear and tear. Furthermore, the ability to promptly detect and resolve defects avoids the high cost of repair and replacement due to track failures later on.
Cooperation Outlook
The successful collaboration between VSNDT Y-series industrial endoscope and a renowned rail manufacturer in Chengdu has set a good example for quality inspection in the rail transit industry. Going forward, both parties plan to further deepen their collaboration and continuously optimize the performance and functionality of the endoscopes based on the emerging demands of rail production inspection. For example, they plan to develop software features more suitable for specialized rail inspection scenarios and enhance the endoscope's anti-interference capabilities in complex electromagnetic environments. Furthermore, VSNDT will leverage the experience gained from this collaboration to further expand its market share in the rail transit sector, providing high-quality inspection solutions to more rail manufacturers and operators, and jointly promoting the safe development of the rail transit industry.
