1 Introduction:
Not affect the production schedule, the on-line eddy current flaw testing system is installed in the production line, to test if there is any crack, air hole, slag inclusion etc. for the workpiece, which makes the producing and detecting can be finished at the same time.
The whole set of system includes detector units, machinery, electric, pneumatic and associated accessories, totally five parts. Adopting self-research eddy current testing technology of IDEA company, using the independence plane analysis and multiple image phase amplitude zone alarm technology, it can automatically find out the defects, and finish alarm, marking and sorting signal output.
2 Tested object: seamless tube, longitudinal welded tube, bar, wire rod, and profiled bar etc.
3 Tested material: carbon steel, stainless steel, copper, aluminium, titanium etc. different kinds of nonferrous and ferrous metals.
4 Testing speed: 0-350m/min
5 Testing mode: 1) Through type probe, the workpiece pass through the eddy current probe
2)Segment probe, the probe is installed on the surface of the workpiece
6 Testing standard: GB/T 7735-2004
GB/T 11260-2008
YB/T 4083-2000

1. Not affect the production speed at all.
2. It can accurately finish defects testing, alarm and marking while high-speed production.
3. Applying electromagnetic detection principle, eddy current detecting is non-touch testing, and won’t cause any effect to the appearance and quality of the workpiece.
1 Metallurgy, machinery, such as cold drawn seamless tube, copper tube of the air-condition, longitudinal welded tube and titanium tube etc.
2 Bar such as cold drawn steel bar and high-precision aluminum bar etc.
3 Wire rod like spring steel wire, bearings steel wire, wolfram wire and molybdenum wire etc.
4 Profiled bar like hollow aluminum crosser, automobile aluminum flat tube.
Adopted with the digital integrated technology, eddy current technology, optoelectronic technology and micro processing technology, the intelligent digital eddy current detector (IDEA-ET0X) is the high-tech full automatic electronic testing machine. Equipped with the delicate mechanical transmission, it makes us well-known as the exclusive domestic NDT detector supplier with complete set of automatic testing system. With the software coded by the windows platform, it is easier and more intelligent for testing. Besides, the instrument is featured with stable and reliable performance, full-automatic testing and fast testing speed. It especially used in high-speed on-line testing for metal, tube/pipe and wire rod.
