The founding principle of TCK weak magnetism inspection technology is the “Spatial Magnetic Field Vector Resultants”theory.

As an innovative and proven NDT technology,it adopts large air-space and non-contact weak magnetic testing devices(see Fig.1 and Fig.2),and is capable to detect quantitatively both internal and external flaws of the test wire rope by monitoring and extracting signals of magnetometive force changes of the test wire rope,which is preconditioned by TCK weak magnetic loader.

TCK weak magnetism inspection instruments comply with intermational testing and evaluating standards(ISO3154 1988) for wire ropes.By testing magnetometive force changes of the countiess cross sections of the test wire rope,which reflect the synthetical degeneration status of each cross section,it provides the needed scientific and technical reference for evaluating in-service wire rope’s residual bearing capacity,safety co-efficient and service life.

Note:Magnetometive force change is the distribution and variation of the magnetic field.A cross section element is the axial segmentation differential of the wire rope.The synthetical degeneration status of a cross section’s bearing capacity reflects both LMA(Loss of Metallic Area)and LF (Localized Flaws).
