Problems solved by technology
[0002] At present, when detecting the presence or absence of ferromagnetic impurities in copper pipes or the continuity of copper pipe materials, eddy current detectors are usually used. The eddy current detectors are based on the eddy current detection method, that is, the eddy current detectors induce eddy currents in the pipes to be tested. , if the pipe to be tested is cracked and discontinuous, the eddy current will change abruptly. Due to this feature, the eddy current detector is very effective in detecting uniform materials with a smooth surface, but it is not smooth in the detection of non-uniform materials containing ferromagnetic substances. False alarms are easy to occur when the material is used, resulting in inaccurate detection, affecting the detection effect, and reducing the detection efficiency

The eddy current detectors are based on the eddy current detection method, that is, the eddy current detectors induce eddy currents in the pipes to be tested. , if the pipe to be tested is cracked and discontinuous, the eddy current will change suddenly. Due to this feature, the eddy current detector is very effective in detecting uniform materials with a smooth surface, but it is not smooth in the detection of uneven surfaces or containing ferromagnetic substances. False alarms are easy to occur when the material is used, resulting in inaccurate detection, affecting the detection effec...
