magnetic particle inspection

n
(General Engineering) engineering a method of testing for cracks and other defects in a magnetic material, such as steel, by covering it with a magnetic powder and magnetizing it: any variation in the concentration of the powder indicates a flaw in the material

These products are used for nondestructive testing practices such as visual inspection, liquid penetrant and magnetic particle inspection. The catalog contains information on UV-A inspection lamps and super-high intensity UV HID lamps.
Magnetic particle inspection is quick, inexpensive and sensitive to defects, particularly shallow (0.003 in.
Ultrasonic testing, magnetic particle inspection, liquid penetrant testing, X-ray inspection and hydrostatic pressure testing are performed at LTI.
Magnetic Particle Inspection is conducted on ferro-magnetic materials, by inducing a magnetic field into the test piece, and is ideal for detecting cracks, porosity, seams and other surface breaking, as well as sub-surface discontinuities down to 2mm.
While stress corrosion cracking mapping and sizing requires conventional eddy current or magnetic particle inspection for location and then a sophisticated ultrasonic technique for sizing, flexible eddy current arrays allow for automated area scanning to speed combined mapping and sizing of entire colonies.
Magnetic particle inspection is one method implemented to find cracks at or near the surface of a casting (Fig.
The Lab was first Nadcap accredited for nondestructive testing in 1992, and currently has a scope that includes liquid penetrant testing, magnetic particle inspection and ultrasonic testing methods.
