Industry introduction

As one of the five conventional non-destructive testing methods, eddy current testing technology is widely used in non-ferrous metal processing, including copper tube testing, copper rod testing, copper wire testing, aluminum tube testing, aluminum rod testing, titanium tube testing, flat tube testing, deformed pipe wire testing and many other aspects. In recent years, with the development of computer, instrument and digital signal processing technology, the application of automated eddy current non-destructive testing technology in non-ferrous metal processing industry has made new progress.

Eddy current flaw detection technology can simultaneously use rotary probe to detect long pass damage, slow change damage and other long strip defects (such as longitudinal cracks) and through the probe to detect spot defects (such as through holes, pits, circumferential cracks), as well as iron inclusion and other special defects, can be widely used in metal pipe, bar, wire, wire online and offline high-speed flaw detection detection.

Case application: copper and aluminum processing

The eddy current testing method is used for non-destructive testing of non-ferrous metal tubes and rods, which is characterized by fast detection speed, high sensitivity, no coupling agent and easy to realize automatic testing.

The through and rotating eddy current flaw detector of  Cangxin Company has been widely used in various fields of non-ferrous metal processing industry, especially for the quality inspection of various pipe and rod wire products, which can effectively detect various types of common and typical defects such as through holes, pits, circular cracks, longitudinal cracks, iron inclusions, etc. The detection speed can reach more than 100m/s. The degree of automation is very high.
