Magnetic particle inspection For Magnetic Particle Testing to Find Defects in Magnetic PartsThis reference guide will provide you with a general overview of performing Non-destructive Testing by the magnetic particle method. The use of this method results in finding defects which are not otherwise visible to the eye. By using Magnaflux equipment, materials, and accessories you are able to locate such inherent and processing defects as: inclusions, seams, laminations, shrinks, cracks, hot tears, laps, flakes, welding defects, heat treat and grinding cracks, machining tears, quenching and straightening cracks and also fatique or service cracks on parts from service.This inspection is important to the quality of the finished product, and in finding defects as early as possible in manufacturing, to avoid wasting machining and processing time on defective material.This reference guide or parts thereof may not be reproduced in any form without written permission from Magnaflux.For full information, refer to “Principles of Magnetic Particle Testing” by C.E. Betz (which can be purchased from Magnaflux)Magneticparticle inspection 3©2011 Magnaflux Open Magnet 1. An open magnet has two poles:North and South. The magnetic field between the two poles will attract and hold a nail.Partially Closed Magnet 2.Bend the ends of the open magnet until they almost touch and the magnetic field between the poles will hold iron powder.3.Bend the magnet until it is completely closed and fuse the ends. Now the magnet will not attract or hold iron powder because there is no polarity and the magnetic field is in a circle inside the ring. This is circular magnetization. 4. A crack part way through the magnet will cause polarity and a magnetic field at the crack, which will hold iron powder and build up an indication of the crack. This is the principle of producing indications by means of circular magnetization.N SHow Magnetic Particle Inspection Works4MPI Reference GuideHow Magnaflux ® Equipment Uses Electricity to Provide Circular Magnetization For Locating Lengthwise Cracks 1. Electric current passing through a wire creates a magnetic field around the wire. Direction of the field is at 90° to the direction of the current. 2.Electric current passing through a ferrous part creates a magnetic field within the part. This is circular magnetization—used to detect lengthwise cracks.In magnetic particle inspection, circular magnetization is used to detect lengthwise cracks.3. Part to be inspected is “set up” in the Magnaflux ® unit and electric current is passed through the part or through an electrical conductor within the part. The circular magnetic field cutting across the crack attracts and holds iron powder, to indicate the invisible defects.Electricity is passed thru the part parallel to the defects to be found.

Electric Current passing through a wire wound into a coil creates a magnetic field lengthwise inside the coil.2. When a part is placed in a Magnaflux ® Unit inside a coil carrying electric current, a magnetic field running lengthwise of thepart is created. This is LongitudinalMagnetization.In Inspection Longitudinal Magnetization is Used to Detect Transverse (crosswise) Cracks.3. Part to be inspected is “set up” in the Magnaflux ® Unit and electric current is passed through a coil around the part. Small parts should not be centered within the coil, but held close to it where field strength is strongest. The longitudinal magnetic field cutting across the crack attracts and holds iron powder to indicate the crack.Electric current is passed around the part, parallel to the defects to be found.WIRE COIL MAGNETIC FIELDCURRENT Magnetic particle indication of transverse crack in a cylindrical part.COILCURRENTCRACKMPI Reference GuideMagnetic particle recommended usageconcentrationsFigure 1PRODUCT FORM RECOMMENDEDCONCENTRATION SUSPENSION MEDIUM14A Powder1/6 oz/gal1.25 g/l Water* Oil14A Redi-Bath Liquid Concentrate 2.7 oz/gal21 ml/lWater Only20B Preblended Powder 1.5 oz/gal11.25 g/lWater Only14AM Ready to use PremixedBath or AerosolReady to Use OilMG-410Powder1/10 oz/gal0.75 g/l Water* Oil7C Black Powder 1.25 oz/gal9.36 g/l Water* Oil7HF Black Ready to use Aerosol Ready to use Oil*Use of water conditioner is necessary to disperse the magnetic particle powderin water.The recommended settling time in a settling tube is 60 minutes for oil baths and30 minutes for water baths.The recommended particle concentration for fluorescent magnetic particles is0.1 to 0.4 ml in a 100 ml bath sample (settling tube).The recommended particle concentration for nonfluorescent magnetic particlesis 1.2 to 2.4 ml in a 100 ml bath sample (settling tube).6Magneticparticle inspection 7©2011 Magnaflux Preparing the Oil BathApplicable To: Magnaglo, 14A, MG-410, Magnavis ®, 7C.Electric Current + Bath + Discontinuity = Magnetic Particle Indication 1.

Iflower, add concentrate.Note:•Do not include dirt particles in your centrifuge Tube readings.•It’s a good idea to check particleconcentration once a day.Change the bath regularly —about once aweek—or up to once a month if bath is notcontaminated or if inspection volume is low.MPI Reference GuideApplying the BathElectric Current + Bath + Defect = Magnetic Particle IndicationsThere are two methods for applying the bath:A.Continuous Method—Current and bath applied together; in other words, themagnetic particles are on the part while magnetizing current is beingapplied.1.Flow bath through nozzle over the part.2.Stop the flow by releasing the nozzle.3.Close the current switch to apply current at thesame instant you release the nozzle.4.Current passes immediately through the part whilebath particles are still draining heavily over thesurface.Be sure the current strength is high enough to showexpected defects, but not so high that particles build upalong flow lines or at any change of section.B.Residual Method—Bath is applied after current has beenshut off; that is the magnetic particles are on thepart when residual (remaining) magnetic field ispresent.1.Pass current through part or through coil tomagnetize the part.2.Shut off current. This will leave a residual magneticfield in parts of hard (retentive) steel.3.Apply the bath using the hose, or by dipping thepart in a separate tank of agitated bath.Note: The Residual Method can be only used on hard steels—which “hold” a magnetic field- usually high carbon or alloy steels, especially in the hard state.For full information, see chapter 14 “Principles of Magnetic Particle Testing.”SWITCHSWITCHOR10Magnetic particle inspection11©2011 MagnafluxDemagnetization of PartsAfter Inspection, Parts are usually Demagnetized.Alternating current coil is usually used on A.C. units. Use of the coil is preferred over using contacts. On D.C. units, use either an external demagnetizer (type S or SB coil) or the A.C. or D.C. demagnetizer built into some units.A. Coil Demagnetization1. Put part in coil.2. Turn on Current.3. Draw part out at least 3 feet away fromcoil while current is on. For greater effect(if needed) rotate part end-for-end whilewithdrawing.4. Check for residual magnetism with aMagnaflux field indicator. Needle deflectionshould be slight (usually less than 3 Gauss.)Caution: Do not turn off the current untilthe part is out of the magnetic influenceof the coil or demagnetization will not becomplete.B. Theory: Demagnetization is accomplished bya reversing polarity field in the part. This fieldis progressively reduced from high to lowstrength in small steps.Drawing the part out of the high strength A.C. field in the coil above results in less and less field with each current cycle (at 60 cycles. per second) until very little field remains in the part.For more information see chapter 17, “Principles of Magnetic Particle Testing.”4 ft. to5 ft.MPI Reference GuidePortable Power PacksFor Magnetic Particle Testing to Find Defectsin Magnetic PartsMagnaflux offers two (2) types of portable power packs: the P-70 which puts out 750 amps, and the P-1500 which puts out 1,500 amps. However,portable equipment is available in a variety of sizes and input voltages andamperage outputs.Portable equipment makes testing in inaccessible areas possible. The main difference between stationary equipment and portable equipment,besides the lower amperage rating, is the omission of the step-down transformerused for demagnetization. This does not limit the use of the equipment sincethe demagnetization still can be accomplished by manually decreasing thecurrent or the number of cable windings can be reduced by one.12Magneticparticle inspection 13©2011 Magnaflux CURRENT PROD POWDER ATCRACKMAGNETIC PARTICLE INDICATION OF CRACK IN WELD OR CASTING WALLPRODHow Magnetic Particle Inspection Works Using Circular MagnetizationHow Magnaflux ®Uses Electricity to Create CircularMagnetic Field in the Part.1.

A crack which cuts across the magnetic field attracts the magnetic particles to form an indication which may indicate a defect.Current is passed around the part parallel to the defects to be found.For full information, refer to “Principle of Magnetic Particle Testing.”CURRENT MAGNETIC FIELD WIRE COIL WIRE COIL CURRENT PART CURRENT CABLE CURRENT POWDER AT CRACK 14©2011 Magnaflux Magnetic particle inspection15How Magnetic Particle Inspection Works Applying The Magnetic ParticlesFirst, apply current.MagnaVis ® dry powder must be dusted lightly andgently to the magnetized area. Watch for indicationsto form as the powder is applied.Gently blow off the excess powder, while themagnetizing current is still flowing.MagnaVis ® magnetic particle powder is availablein four colors: red, black, yellow, and grey. Select thepowder which gives the best color contrast with thepart being inspected.If the Magnaflux ® Powder Blower is used, it appliesthe powder in a gentle cloud and also has a lowpressure air stream to blow off excess powder.Powder may also be applied by using powder spraybulbs or disposable plastic squeeze bottles.A liquid suspension of fluorescent or non-fluorescentmagnetic particles may be used instead of drypowder. Premixed baths of either type particles areavailable in aerosol or in bulk for application byportable applicator guns or in pressured spray cans.If a wet bath is used with cable magnetizing, besure to follow agitation instructions for the inspectionmedium.MPI Reference GuideWeld Inspection1.Firmly hold prods along weld, spaced from 4 to 8 inches apart andstraddling the weld.2.By turning on the magnetizing current, the area of the weld between theprods becomes magnetized.3.While the current is flowing, lightly dust powder over the magnetizedarea. Watch for indications to form.4.Gently blow off excess powder.5.Stop current flow and look for indications.6.Move prod tips along the weld (see diagram below) repeating all steps.Be sure that each spacing overlaps the previous shot.Moving along the weld in this manner should bring out any cracks in the weld oralong its edges which are parallel to the weld.Be sure to:1.Press prods firmly to the surface to prevent arcing.2.Keep the current flowing until the excess powder has been blown off.3.Overlap the areas inspected.4.Reduce field strength if particles accumulate excessively at prod points.5.Increase the field strength if there isn’t some noticeable magneticinfluence of the particles at the prod tips.Field strength can be increased by increasing the strength of the magnetizingcurrent or reducing the distance between prods.NOTE OVERLAPWELD INSPECTION SHOWING OVERLAP OF SHOTS NECESSARY FOR COMPLETE TEST16©2011 MagnafluxMagnetic particle inspection17Inspecting Large AreasThe inspection of a large area is accomplished by inspecting many smaller areas in sequence.With the prods spaced 8" apart, an oval shaped magnetic field will be created for adequate inspection. The magnetized area will be about 4" wide. To completely inspect a large area for cracks in one direction prod spacing will look like this:For complete inspection the entire area will have to be covered in this manner and then the process must be repeated with prod positions at 90° to the first direction.Follow the six operations shown onpage 16 for every prod spacing.Critical areas such as change ofsection in complicated casting orfabrications should be inspectedbefore finishing operations areperformed. Then repairs can bemade more easily. The direction ofthe magnetic field should be atright angles to the crack for bestdetection.DIRECTION OF CRACK BEST DETECTED DIRECTION OF CRACK BEST DETECTEDMPI Reference GuideUsing Cable CoilsTo look for transverse (crosswise) cracks in shaft or pipe.1.Wrap 3 to 4 turns of cable loosely around part keeping each turn closetogether.2.Turn on magnetizing current.3.While current is flowing, lightly dust MagnaVis® powder onto themagnetized area. Watch for indications to form.4.Gently blow off excess powder.5.Stop current flow and examine surface for indications.Such cable wrapping usually will create an effective magnetic field from 6" to8" on either side of the coil. If the part is long you will have to move the cablealong from the first position and repeat the 5 steps of magnetization and powderapplication until the whole length of the part is covered.To Inspect Hollow Parts1.Thread 3 to 4 turns of cable through eye of part keeping turns close toeach other and to the part.2.Turn on magnetizing current.3.While current is flowing, lightly dust powder to the magnetized area.Watch for indications to form.4.Gently blow off excess powder.5.Stop current flow and examine surface for indications. Move cablearound the opening to examine area which was under the cable in thefirst operation. Repeat all 5 inspections steps above.18Magneticparticle inspection 19©2011 Magnaflux DemagnetizationUse aC Current for Demagnetization1. Make a 3 to 4 turn coil loosely around the part.2. Energize the coil.3. Remove the coil from the part, or the part from the coil, at a distance of at least three feet.4. Turn off the current.Caution: Do not turn off the current until the part is out of the magnetic influence of the coil or demagnetization will not be complete.The coil should be energized with a current as strong or stronger than that used for magnetization.。
