Wire Rope Defectography Test

A TO Z has been providing Wire rope testing which is a form of electromagnetic inspection using equipment designed specifically for steel braided wire rope

The equipment utilizes two strong magnets in a clam shell type set up to clamp around the rope. These magnets create a constant magnetic field in the steel rope. Since the magnetic field is constant, the amount of flux necessary to saturate the rope is a function of the cross-sectional area of the rope.

If the section of the rope that passes through the machine contains defects such as broken wires, corrosion thinning or stretching, the magnetic flux will be affected. These changes are interpreted on an oscilloscope display. and determine the percentage of cross-sectional loss, broken wires, and overall loss of break strength.

Steel rope is used in a variety of applications such as amusements parks, mine shafts ,mine rope, suspension bridges and overhead cranes.
