This paper presents an advanced Barkhausen Signal NDT system, which detects flaws and micro-structural changes affecting strength in steel wire rope. This technology enables early detection of flaws long before they become visible. Monitoring is conducted in real time and is non-contact. In this study, 20 defects of various types were introduced into a new rope. All defects were detected and their effect on strength tested. Some of these defects lowered the strength of the wire rope by 50%.
