System design
1 Introduction
This off-line eddy current detecting equipment is used in high accuracy flaw testing for workpiece that already be finished.
Automatic testing procedure: Using up-loading system, via roller way, the workpiece was sent to the eddy current detecting area, through magnetic saturation, probe, and demagnetization device, finally the off-loading system. Meantime it can automatically alarm, mark, sort according to the testing result.
2 Tested object: tube, bar, profiled bar
3 Tested material: carbon steel, stainless steel, copper, aluminium, titanium etc. different kinds of nonferrous and ferrous metals.
4 Testing speed: 0-100m/min
5 Testing mode: off-line flaw detecting
6 Testing Standard: GB/T 7735-2004
GB/T 11260-2008
YB/T 4083-2000
