System Design

1. System Introduction

This is the rotary eddy current testing system , the testing work pieces will be automatic put on the up-loading platform ,then go directly to the ROTA eddy current testing parts for testing,then according to the testing results , the workpieces will be automatic off-loading and sorting to qualified area and unqualified area

 This testing model is high sensitive to the longitudinal defects, it is the best solution for the whole workpieces’crack testing , and also with the high accuracy and stability.

 2.Testing object: steel tube , steel bar , steel wire

3.Testing material : Carbon steel ,stainless steel,copper,aluminium,titanium and different kinds of non-ferrous and ferrous metals

 4. Testing speed : 0-100m/min

 5. Testing model : Off-line Rotary eddy current testing system

6. Testing Standard : GB/T7735-2004 Steel tubes-The inspection method on eddy current test.

                                        ISO 9304-1989 --- Seamless and welded (except submerged arc-welded) steel tubes for pressure purposes--- Eddy current testing for the detection of imperfections

                                       GB/T 11260-2008Round steel-the inspection method for eddy current test

                                       YB/T 4083-2000Measurement method of comprehensive properties for automatic eddy current flaw detection system for steel tubes
