TROY, MI-Test Equipment Distributors (TED), a supplier of nondestructive testing equipment and supplies nationwide, announces the acquisition of the supplies and accessories business unit of Universal NDT (Upland, CA).
At ibg NDT, a new eddy current instrument can detect multiple types of surface flaws simultaneously with no resolution loss for any of the types. Bill Buschur, general manager of ibg NDT Systems Corp. (Farmington Hills, MI), likened it to radio: listeners can clearly hear only one station at a time-or in the case of eddy current, only one flaw type at a time-because multiple radios tuned to multiple stations produce only unintelligible noise.
Since writing my last note for October, I have been traveling yet again, to Spain, Morocco and, of course, the Midwest. I flew into Detroit three times since writing that column, attending the MS&T show at the end of September, a Powertrain Engineering and Manufacturing Alliance (PEMA) press conference in October, and finished the year with a computed tomography lab open house in December.
Eddy current inspection is a versatile nondestructive testing technique. It allows accurate measurement and evaluation of the conductivity and, therefore, the chemistry, hardness and geometry of any electrically conductive material that is brought into the proximity of a coil of wire.
Maximizing product output and production efficiency without compromising quality is a cornerstone for any successful manufacturing company. A company’s reputation and brand perception in part rests on its ability to produce a quality product consistently and efficiently over time. Remington Arms, founded in 1816 in upstate New York, is one of the nation’s oldest continuously operating manufacturers of firearms as well as one of the largest rifle and shotgun makers in the world. As such, there is a lot riding on the company’s reputation.
Ultrasonic nondestructive testing (NDT) is a versatile technique that can be applied to a variety of material analysis applications. While ultrasonic NDT is perhaps better known in its more common applications for thickness gaging, flaw detection and acoustic imaging, high frequency sound waves also can be used to discriminate and quantify some basic mechanical, structural or compositional properties of solids and liquids.
Computed tomography systems for industrial applications, such as R&D, production and quality, can see inside parts and quantify characteristics normally inaccessible to probing or optical sensors. The same dataset can be used to inspect the structure of material, such as porosity or wall thickness; measure external features; and generate fully surfaced or solid computer-aided design (CAD) models.
Turnkey inspection systems are designed and built to meet the customer’s specific inspection application, for parts as small as bolts and nuts or as large as I beams or engine blocks. These systems are often designed around eddy current-based inspection products, but also can include magnetic flux leakage technology, ultrasonic technology or vision systems, all operating together to perform a fully automated inspection process. The systems can be integrated into any manufacturing operation so there is minimum information lag between when a defect occurs and when it is detected.
The Targa III Dynamic Runout instrument measures runout on high-speed spindles at speeds up to 300,000 RPM. The new instrument has a noncontact capacitive sensor and a digital display with multiple measurement modes. The dynamic runout mode (DRO) presents a continuously updating TIR measurement that does not require manual reset when the TIR decreases. This feature allows measurement of DRO across a range of spindle speeds. Results of this test indicate the optimal speed for production operation of the spindle.
