In this video Magnaflux’s Brian Batteiger goes through the common steps of magnetic particle inspection on ferrous parts as outlined in ASTM E1444: Standard Practice for Magnetic Particle Testing. The specific sequence of steps may vary depending on the method of particle application, here we outline the steps in wet magnetic particle application, continuous method.
Just like all nondestructive testing methods, the results of a mag particle inspection are only reliable if the testing is performed accurately and consistently.
This is meant to provide a general overview of a typical MT / MPI process; all NDT testing must be performed in accordance with the prescribed specifications or test procedures.
