In order to ensure the safe operation of the wire rope, scientists from all over the world have been carrying out unremitting exploration and research in the field of wire rope nondestructive testing. The nondestructive testing of steel wire rope can be divided into magnetic testing technology and non-magnetic testing technology. Today, we will first understand the non-magnetic detection technology.

Non-magnetic testing technology for wire rope nondestructive testing technology

In order to ensure the safe operation of the wire rope, scientists from various countries have beenNDT for wire ropeaspects of unremitting exploration and research. The nondestructive testing of steel wire rope can be divided into magnetic testing technology and non-magnetic testing technology. Today, we will first understand the non-magnetic detection technology.

Non-magnetic detection technology is generally used under specific technical conditions. Due to the harsh conditions for the formation of the testing media involved, the complexity of the technology, and the high cost of equipment and use, it was only praised for a while in terms of academic achievements, and then did not really obtain the practical application of wire rope nondestructive testing.

eddy current testing technology:

Invented by the French in 1976, its detection sensitivity is very low, and it can only qualitatively detect defects such as broken wires outside the wire rope;

1. Acoustic emission detection technology: invented by the British in 1984, using the principle of acoustic emission for qualitative detection of steel wire rope, because it can only be used for deep sea and other special environment detection and can not be widely promoted;

2. Optical detection technology: invented by the Germans in 1987, mainly using laser scanning and optical sensor technology to qualitatively deduce the damage status of steel wire rope by measuring the change of rope strand diameter;

3. Ultrasonic testing technology: invented by the Japanese in 1988. It mainly uses the reflection characteristics of ultrasonic waves and ultrasonic sensor technology to carry out qualitative nondestructive testing of steel wire ropes. It can only carry out general testing of local defects of completely stationary and suspended steel wire ropes, and it has not been widely used in industrial fields;

4. Transverse excitation vibration wave detection technology: invented by Americans in 1988, mainly using transverse excitation vibration wave and vibration wave sensor technology to qualitatively detect fixed wire ropes. Its industrial application is similar to the above-mentioned detection techniques.

Non-magnetic detection methods or because the detection signal is susceptible to interference, the test results are difficult to record, or because the equipment cost is too high, the detection limitations are too large, have not been popularized and applied, is still in the laboratory research stage.
