NDT Magnetic Particle Inspection
Aqualified LLC provides NDT Magnetic Particle Inspection and Testing in the Dry and Wet Fluorescent form. MPI Magnetic Particle Inspection provides flaw detection of surface and subsurface defects in ferrous materials.
We provide qualified and certified NDT Level 2 and 3 MT Magnetic Particle Inspectors in accordance with NAS-410, SNT-TC-1A, ACCP or CP-189. We can perform your inspection, provide MT OJT or teach you how to provide the service for yourself. Aqualified NDT Advocates strive to bring success to you and your establishment. Common codes for MT include ASTM E-1444, E-709 and ASME Section V Article 7.
Our NDT Advocates can perform your Magnaflux Magnetic Particle inspections, create techniques, provide pre-audit support, perform vendor audits and surveillance, qualify NDT inspectors and establish your NDT program, including providing personnel augmentation and shift support during extreme workload conditions.
Magnetic particle inspection is commonly performed on hooks, bolts, nuts, rails, castings, valve bodies, pumps, forged parts, control arms, breaks, generator parts, welds, impellers, lifting hardware, forks, latches, pins, bearings, railroad carts, billboards, ships, automobiles, structural steel, pipes, tubes, gears and any other ferromagnetic material.
Iron particle testing equipment available includes wet horizontal bench, yoke, coil, cable wrap, prods and permanent magnets. Both visible and fluorescent MPI processes are available in AC, HWDC and FWDC. The sensitivity and reliability of the ndt iron particle inspection process is dependent on the proper selection of the equipment.
A key component of magnetic particle is to ensure that you do not leave the part magnetized. Magnetized parts will attract ferrous materials and may interfere with welding processes. When inspecting engine parts and aircraft components, demagnetization is very important because magnetic fields can increase wear or alter an aircraft’s compass causing erroneous navigation data. Sometimes aircraft get magnetized by lightning and the antennas have to be demagnetized with a DC magnetic yoke.
Field strength measurements of magnetic resonance can be useful in determining the extent of magnetization for a given test component, or also verifying the extent of demagnetization. Gauss meters are used in many applications to determine if an article has been sufficiently demagnetized after testing. If the demagnetization process is ineffective, subsequent processing may be affected. Residual magnetization may affect equipment when the component is placed into service.
When you call on Aqualified you don’t have to worry about a thing. Our inspectors are properly qualified and certified, our light meters and instruments are calibrated, and the inspector is versed on using a pie gage, hall effect probe, or QQI as needed. We can bring our own dark room and generators and set up anywhere needed.
