Reliable Nondestructive Testing
Magnetic Analysis Corporation (MAC®), Elmsford, NY, USA, a pioneer in nondestructive testing solutions, helps wire mills tackle challenges through its Minimac® digital eddy current test equipment. Union welds, an unavoidable byproduct of high-speed wire production, can present a significant hurdle for wire manufacturers. These defects have been rejected outright by end-users, making it essential for manufacturers to detect and remove them during production. MAC’s Minimac digital eddy current test instrument has become an answer for wire manufacturers facing these quality rejects. The Minimac, designed for high performance and cost-effective detection of these union welds, has recently helped a premier wire mill in Mexico. After a successful on-site demonstration, the company incorporated five Minimac systems into its production line. These systems now inspect insulated copper cables ranging from 2.5 to 10 mm in diameter, ensuring that defective sections are identified and removed before shipment. The Minimac features advanced encircling coil sensors and a CP65NS coil platform, which ensure accurate positioning and vibration control during high-speed testing (currently operating at 120 meters per minute). The results have been remarkable. Customer returns due to weld defects have been virtually eliminated.
