Wire rope is a flexible component widely used in engineering, which is widely used in coal, metallurgy, petroleum, forestry, port, construction, tourism, bridge construction and other industries. Just like other engineering components, the wire rope will produce damage in the process of using, and the safety of its use has been a long-term concern. Since the first wire rope electromagnetic nondestructive testing device was developed in South Africa in 1906, it has now developed more than ten methods of optical, ultrasonic, eddy current, mechanical, electromagnetic, ray, penetration, etc. for nondestructive testing of wire ropes. Among them, manual visual inspection is a very original method, but because of its simplicity, it is still used, but its reliability is poor; electromagnetic nondestructive testing method is recognized as a very reliable and very easy to achieve detection method in the world, the current use of wire rope nondestructive testing technology and instruments almost all use electromagnetic testing method.

Wire rope is a flexible component widely used in engineering, which is widely used in coal, metallurgy, petroleum, forestry, port, construction, tourism, bridge construction and other industries. Just like other engineering components, the wire rope will produce damage in the process of using, and the safety of its use has been a long-term concern. Since the first wire rope electromagnetic nondestructive testing device was developed in South Africa in 1906, it has now developed more than ten methods of optical, ultrasonic, eddy current, mechanical, electromagnetic, ray, penetration, etc. for nondestructive testing of wire ropes. Among them, manual inspection is a very original method, but because of its simplicity, it is still used, but its reliability is poor; electromagnetic non-destructive testing method is recognized as a very reliable and very easy to implement detection method in the world today.Non-destructive testing of steel wire ropeTechnology and instruments almost all use electromagnetic detection methods.

At present, the domestic wire rope non-destructive testing market, mainly to sell domestic and foreign non-destructive testing equipment, many users have purchased testing equipment, but can not really play its role. The reason is that it is not easy to achieve accurate detection of wire rope defects, especially quantitative detection. American wire rope testing expert Dr. H.R. Weischedel once said: "The quantitative detection of wire rope defects is very difficult, if not impossible."

This is mainly due to the complexity of the structure of the wire rope itself and the inferiority of the field conditions, the limitations of detection methods and equipment. Wire rope nondestructive testing is only an auxiliary detection means, it can help us quickly, accurately and comprehensively find defects. We also need to analyze the type and severity of defects, accurately judge the current situation of wire rope, and take corresponding measures to improve the operation of wire rope to prevent further deterioration of damage. This not only requires the equipment to have good resolution and accuracy, but also requires the inspection personnel to have a comprehensive understanding of the wire rope structure and its defects, and to evaluate the defect state on this basis. Obviously, relying solely on the purchase of wire rope non-destructive testing equipment, users to detect their own, it is difficult to get accurate and scientific testing data, it is impossible to clear the use of wire rope judgment and deterioration trend prediction.
