Re: [MW:25744] RE: 25727] MPI on painted joint

Alan thanks
But I think it's possible cause we have magnetic test method to detect paint coating thickness so it's possible to carry out MPI on a painted joint. I really want to know if there is a code reference or a publication that might say something like that.  Thanks for your contribution I do appreciate.

My experience is that it does not work,  and this is not surprising. I have had eddy current testing used over painted surfaces to detect underlying cracks with good results, in that cracks were reliably detected. You would need to trial it with coatings on the calibration block.
