How to Use Eddy Current Technology to Test Ferrous and Non-Ferrous Wire” Authored by Troy Libby, Engineering Manager
Eddy Current inspection is a technique used for detecting surface seams, cracks, pits, slivers, and internal discontinuities in ferrous and non-ferrous wire. Different test sensor configurations, including encircling coil and rotary probes, can be used. When using encircling coil eddy current testing, the wire passes through the coil excited by an alternating current with one or more drive signals.

MAC® at the 2024 Pipe and Tube Conference in Omaha
Magnetic Analysis Corporation (MAC®) is excited to announce its participation in the 2024 Pipe and Tube Conference, taking place on November 13-14 at the Kimpton Cottonwood Hotel in Omaha, Nebraska. This year’s conference promises to be a dynamic gathering for industry professionals, featuring insightful sessions on cutting-edge technologies and networking opportunities.
AUTOMOTIVE TUBE
Precision tubes for the automotive industry must meet the highest performance requirements. MAC’s® Eddy Current, Flux Leakage and Ultrasonic systems are often used to inspect tubes destined to be cut into short lengths to be fabricated into a critical automotive component.
WIRE AND ROD
Eddy Current technology is the go-to wire and cable testing method for checking continuity, alloy, surface flaws and other conditions as well as for locating welds and splices. MAC® instruments can handle a range of metal wire including cut lengths, continuous production, stranded, multi-conductor and insulated cable.
WELDED TUBE
There are many welding processes and many tubing configurations and sizes. MAC has extensive experience testing tubes and pipes using eddy current, ultrasonic, and flux leakage technologies. We have a large base of testing equipment lines being used to meet the many different ASTM, API, EN, ISO and other industry quality standards and or customer driven quality requirements.
TUBE ENDS
All nondestructive test (NDT) methods have some limitation in regard to testing to the very end of a tube. These “untested ends” must be cut off, resulting in a substantial loss of product and revenue. To avoid this loss, a manufacturer needs to develop a method to test these ends to meet the tube integrity requirement.
