Testing Wire

Eddy Current testing is generally the best choice to inspect wire in line with cold heading operations such as spring making and other parts forming, and for checking continuity, alloy and other conditions. Eddy current tests are also frequently used to locate welds and splices in insulated cable.

The choice of equipment depends on the nonconforming conditions you wish to detect and the size and characteristics of the material. MAC instruments can handle a range of metal wire including cut lengths, continuous production, stranded, multi conductor and insulated cable. Carbon steels, stainless alloys, copper, aluminum, titanium and other non ferrous metals can be inspected.

An example of a system to inspect hot steel wire rod during rolling consists of the Encircling and Rotary combined Rotomac® BQ. This system uses the encircling coils to detect short defects such as cracks at least 0.1mm deep, and the rotary to detect long, continuous defects such as fins and laps. Hot wire rods are fed through the system at speeds greater than 100m/s and sizes accommodated vary from 5-9mm in diameter. The Rotomac BQ rotary may also be added to existing encircling coil systems for testing wire. Custom sizes are based on the application specifications.

Additional items such as markers, controls, demagnetizers and components for mounting the encircling or segment test coils and saturation coils, and positioning and driving the material through the test, are combined with the instrumentation to make up a complete test system.
