Re: [MW:5807] MPI vs DPI

Hi all,          I have to clarify regarding the MPI that can detect sub-surface. I can't see any code or std mention abt how much depth(6mm) can it detect the defects. Please inform me which std mention may i refer?   Thanks & regards, P.Mahendran --- On Wed, 30/6/10, manoj john <manojacgnr@gmail.com> wrote: From: manoj john <manojacgnr@gmail.com> Subject: Re: [MW:5796] MPI vs DPI To: materials-welding@googlegroups.com Date: Wednesday, 30 June, 2010, 8:48 AM Mpi  can be used only on ferromagnetic materials.  It can detect subsurface defects.   DPI can be used on any material.  It can detect only the defects which are open to the surface.
