Re: [MW:5810] MPI vs DPI

Hi, Normal Detection depth in MT shall be 6mm.However maximum detection depth shall be 15mm Very large cracks can be found in normal practice. But as per magnaflux(MT equipment manufacturer) recommendation Normal detection depth - 6mm.However 12mm to 25mm can be acheived.   Thanks & Regards,   (Karthik) Karthikeyan.S   Getabec Energy Co.,Ltd. 379,Moo6,Soi8,Nikhomphatana, Rayong-21180, Thailand.

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.
