With NACE Corrosion 2016 just around the corner, we look forward to showcasing GE’s latest corrosion technology as part of our advanced non-destructive testing (NDT) offerings. More than 5,500 attendees from 70 countries are expected to be in attendance, making it the largest corrosion conference internationally – and a great place for us to connect with industry peers and customers about the corrosion challenges facing organizations today. To check out our wide range of NDT solutions or speak with some of our experts at the conference, stop by booth #1550.
Our experts will explain how our NDT offerings help industrial organizations boost productivity, improve safety and minimize plant downtime. These products include everything from remote visual inspection, ultrasonic testing, radiographic testing and eddy current testing. Corrosion and erosion result in billions of wasted dollars each year in the oil and gas and power generation industries. Detection, sizing and monitoring equipment can help avoid up to 25 percent of those wasted dollars, making it crucial for companies to have the most innovative and effective NDT equipment.
Our NDT technologies help you collect important data and convert it into useful information. Coupled with historical plant data, intelligent software, image enhancement, databasing, applicable codes and additional knowledge, asset owners can make better-informed decisions regarding treatment, mitigation, remaining life, component replacement or plant operating parameters.
Whether you are in oil and gas, aerospace or government infrastructure, our experts can help ensure you are getting the optimal solution to meet your company’s inspection needs. Additionally, we are always taking into consideration customer feedback to build the most productive inspection products in the market and would love to hear from you.
We hope to see you in Vancouver from March 6-10!
Wheel and axle inspection is a fundamental component of high speed railway safety. As more high speed trains become available and the speed at which they transport and the loads that they carry continually increase, the possibility of material failure grows substantially. High profile incidents, most recently in Germany, France and the U.S., demonstrate a significant need for increased safety practices and improved technology to mitigate these risks.
Trains traveling at speeds greater than 200 km/h and urban commuter or metro trains subject their hollow axles to increased strain, which puts their structural integrity and reliability at risk. Fatigue cracks occur in areas where there is a high stress concentration, including the hollow axle, wheel rim, wheel disk, bore hole and gear seat, and the wheel seat. Remnants from the wheel and axle manufacturing process can also cause stress at high speeds, reinforcing the need for inspections to be done accurately on a scheduled and ongoing basis. As a result, hollow axles must be inspected regularly for early detection of flaws to assure the cracks do not propagate quickly.
GE recently introduced technology to dramatically improve inspection quality for the rail industry. The Compact Hollow Axle Tester (CHAT) combines hollow-axle inspection mechanics and ultrasonic angle-beam probes with GE’s high quality ultrasonic instrumentation. GE’s CHAT allows inspectors to perform regular evaluations and create dynamic inspection plans through fast data acquisition and image display with an intuitive interface and advanced software.
Global rail operators conduct inspections at regular intervals, primarily during the night shift to avoid traffic disruptions. The ability to complete a full inspection quickly, without the removal of the wheelset and axles from the car, allows rail operators to increase the productivity of the inspections.

When people think about 3D printing, many assume all printed parts are exactly the same. Additive manufacturers today, however, understand that there is still a considerable amount of variation with 3D printing, and, as a result, advanced inspection methods and tools must be used to ensure printed parts are meeting industry standards.
Because 3D printing is not as repetitive or consistent as it’s often portrayed to be, it requires regular testing and calibration. For this reason, GE developed a scatter|correct function to be used in conjunction with cone beam CT in its v|tome|x m microCT scanner to eliminate the guesswork in additive manufacturing.
Cone beam CT, which images an entire part as it rotates just once between an X-ray source and a detector, is up to 100 times faster than fan beam CT. That’s partially because a fan beam CT scanner X-rays thin slices of a work piece as it rotates and moves linearly in steps through the beam. Those thin slices then have to be reconstructed and combined to represent the full 3D volume. The downside to cone beam CT is that it’s subject to scatter on images.
When GE works with super dense metals, such as chromium cobalt, the radiation causes the materials to scatter resulting in a blurry image. The scatter effect can make it more challenging to get an accurate measurement. Steel, aluminum, composites and multi-material parts are also prone to create scatter on images.
For industrial process control, excellent CT quality at high sample throughput is evident. GE’s proprietary scatter|correct option is a combination of hardware and software advances, allowing users to scan large sample batches in reasonable time as well as significantly reduce scattering artifacts to improve the precision of failure analysis and 3D metrology inspection tasks. The scatter|correct smart function is applied to the first part scanned in a series and the CT scanner applies it to every subsequent part for a clear image and accurate measurement. By combining high precision fan beam CT quality with high throughput of fully automated cone beam CT, the significantly increased inspection productivity allows CT to migrate from R&D applications to serial inspection on the production floor.
