With the development of science and technology, the non-destructive testing methods of wire rope have been acoustic method, electrical method, vibration method, magnetic detection method and so on. The magnetic detection method is currently recognized as a reliable wire rope detection method, but also a more mature method. Next, let's understand its detection principle.

Principle of Non-destructive Testing of Wire Rope

With the development of science and technology,Non-destructive testing of steel wire ropeMethods have been acoustic method, electrical method, vibration method, magnetic detection method. The magnetic detection method is currently recognized as a reliable wire rope detection method, but also a more mature method. Next, let's understand its detection principle.

The non-destructive testing of steel wire rope mainly analyzes the local detection (LF) and cross-sectional area loss (LMA) of steel wire rope. LF defect detection mainly uses the principle of magnetic flux leakage, through the sensor of rare earth magnetic steel from the axial rapid magnetization of the inspected wire rope. LMA defect detection uses the principle of magnetic flux. When the wire rope has internal and external local wear, deformation, and the change of metal cross-sectional area, the change of magnetic flux will occur. Through the analysis of the wire rope signal, the relevant information of the change of cross-sectional area can be obtained.
