This NDE method is accomplished by inducing a magnetic field in a ferromagnetic material and then dusting the surface with iron particles (either dry or suspended in liquid).
Surface and near-surface imperfections distort the magnetic field and concentrate iron particles near imperfections, previewing a visual indication of the flaw.
MIT offers Magnetic Particle Testing (MT) utilizing several method combinations which include fluorescent and visible testing. Our equipment ranges from hand held yokes to a 10’ 6000 AMP Horizontal unit.
Most of our MT services are offered both in house and in the field.
