The Experiment Research of New Electromagnetic Testing Technique in Pressure Equipment Inspection

Electromagnetic testing new techniques include eddy-current testing(ET), magnetic flux leakage(MFL) testing, metal magnetic memory(MMM) testing, micro-magnetic detection and so on. And it was hotspot in the research range of pressure equipments nondestructive testing for the past few years. In this paper, the basic conception, characters and the state of arts of new electromagnetic testing technique were introduced. An experiment on the electromagnetic testing was carried out. Then, some problems and improvement measures were analyzed preliminary for electromagnetic testing technique in pressure equipment inspection.
