Finding Welds In Automotive Wire
Magnetic Analysis Corp. supplies Eddy Current, Ultrasonic, and Flux Leakage test systems to wire and bar manufactures worldwide. Applications include Eddy Current testers for in line testing with cold heading operations such as spring makers and other parts formers. MAC’s MultiMac® Electronics and Rotary Probe can detect long continuous surface and subsurface defects such as seams and welds, while short defects such as cracks and laps are detected using encircling or segmented test coils. By using the Varimac® or Production Comparator eddy current testers, alloy differences, hardness, and heat treatment may be detected in cut lengths or continuous wires. MultiMac can also be used to check alloy, continuity, and locate welds and splices in insulated cable.
MAC instruments can handle a range of metal wire including cut lengths, continuous production, stranded, multi conductor, cold drawn, fine diameter, and insulated cable. Carbon steels, stainless alloys, copper, aluminum, titanium and other non ferrous metals can be inspected.
Additional items such as markers, controls, demagnetizers and components for mounting the coils or rotaries, and positioning and driving of the material through the test, are combined with the instrumentation to make up a complete test system.
