ranging from 0.838 to 6.35mm (0.033" to 0.25") diameter. A noise cancelling test coil and bushings provide improved performance by minimising noise from mechanical vibration in the wire that otherwise might interfere with the test. Minimac II can also be used for testing welding wire, including flux core wire, where missing flux can be detected as well as flaws in the wire itself. Checking continuity and locating welds in single- and multi-conductor insulated wire and cable are other applications. MAC engineers will be present in the booth to advise on these and other possible ways to use Minimac II to solve wire and rod production quality problems. Also on display will be the Rotomac® 25 RM eddy current rotary for on-line inspection for longitudinal surface defects in wire from 3 to 25mm diameter. This rotary is especially applicable for use in spring making, cold heading and similar slow-throughput operations. Information will also be available on the company’s full range of products, including the MultiMac® eddy current tester with up to eight test channels, and ultrasonic instruments and systems.

The Minimac’s versatility is suitable for use in a wide range of test applications in wire and rod mills during production. Visitors to the booth will be able to see a demonstration of the Minimac II testing nitinol wire, an SMA (shape memory alloy) that is frequently used in critical surgical applications such as stents and heart valves. Nitinol wire is often subject to cracks and inclusions, which can form from the melting process during production. Using a Minimac II eddy current instrument with its phase sector output gate and MAC’s wire-tester test coils for small diameter applications, cracks and inclusions can be detected and separate counts for both conditions can be provided, while rejecting only the wire with cracks, for example. MAC can supply test coils as small as 0.013" ID.

Minimac II eddy current instrument for inspecting wire and cable for surface and sub-surface defects and anomalies

Other applications for the Minimac II include testing continuous cast small diameter copper rod, installed just before the coiler, but after the rod is produced and drawn down to smaller diameters. The tester can assess grade, using MAC’s grading software to automatically categorise the quality level of individual segments and entire coils of wire and rod, during production. The customer can customise the defect types, specify the maximum number of defects for each grade level, and configure categorised reports. Based on the report, the producer can draw down higher graded wire to even smaller diameters. Lower grades are not drawn down as much, to avoid problems with breakage in the wire that could end up causing downtime to re-thread the drawing machine. A magnetic inclusion detector (MID), operating in combination with the flaw detectors, can detect magnetic inclusions that are often introduced by steel wire brushes during processing. In another example application, a Minimac II can be installed in a wire mill for finish inspection of zirconium, copper and beryllium copper alloys, to detect defects including surface flaws in plating and sub-surface anomalies in bonding, and inclusions in multiple layers in wire
