Page 8 of 19 8.0 EXAMINATION PROCEDURE 8.1 Scope Magnetic particle inspection is a non-destructive method for detecting cracks and other discontinuities at or near the surface in ferromagnetic materials. Finely divided magnetic particles are applied to the surface of a part which has been suitably magnetized. The particles are attracted to regions of magnetic nonuniformity associated with defects and discon-tinuities, thus producing indications which are observed visually. Sensitivity is greatest for surface defects and diminishes rapidly with depth below the surface. The patterns will be characteristic of the type of discontinuity present.

8.2 Cleanink Prior to magnetic particle examination, the surface to be examined and all adjacent areas within 1" of the surface to be examined, shall be dry and free of any dirt, grease, lint, scale, welding flux, spatter, oil, or other extraneous matter that would interfere with the examination.

8.3 Sequence of Operation Examination shall be done by the continuous method; that is, the magnetizing current remains on while the examination medium is oeing applied and while the excess examination medium is being removed.

8.4 Magnetization Any suitable and appropriate means for establishing the nectssary magnetic flux may be employed, such as passing a current through the material, yoke (for surface discontinuities only), or wrapping the part with a coil through which a magnetizing current is passed.

QoQum Paruae exam.

Page 9 of 19 8.5 Examination Medium Theiinely divided ferromagnetic particles used for detection of discon-tinuities shall meet the following requirements:

8.5.1 Dry Particles - If dry particles are used, the color of the particles (dry powder) shall provide adequate contrast with the background of the surface being examined. Magnetic particle examination shall not be done on the surface of parts whose temperature exceeds 600 F.

8.5.2 Wet Particles - If wet particles are used, the color of the particles shall provide adequate contrast with the surface being examined. MAGNAFLUX 14AM PREPARED BATH in aerosol cans shall be used. This is a factory prepared bath which must be agitated prior to spraying on the examination area. Material certification shall be provided prior to use.

8.5.3 Fluorescent Particles - If fluorescent particles are used, the examination is to be conducted in a darker.s d area using filtered " black light," with an intensity reading at least 90 f t. candles at the work surface, using a Weston 703, Type Ill meter, or equal, without filter in the meter and with a 10X multiplier disk. The " black light" shall be filtered ultra-violet radiation with wavelengths within the range of 3300-3900 angstrcm units such that the particles emit a brilliant fluorescence when subjected to this light. The bulb shall warm up for at least 5 minutes prior to use in exarr.ination.

The black light intensity at the surface under examination, shall be determined at least once every 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> and when-ever the work location is changed.

8.6 Orientation of Discontinuities Whatever method or methods are used to produce the magnetic flux, the maximum sensitivity will be to the linear discontinuities perpendicular d

to the lines of flux. To ensure the most effective detection of discontinuities, each area (stud, nut, weld, etc.) shall be examined at least twice, with the lines of flux in one case approximately perpendic-ular to the lines of flux in the other. More than one methoJ of magnetization may be incorporated to achieve perpendicular lines of flux. ,

8.7 Demagnetization Demagnetization following examination is required where residual mag-netism can interfere with subsequent processes or usage.

Page 10 of 19 8.8 Methods and Procedures Unless specified otherwise, the examiner shall select the examination method, equipment, and particle material which will ensure adequate detection of the specified discontinuity orientation.

8.8.1 Prod Method and Procedure (1) Examination Medium - Magnetic particles in dry form shall be used with the prod method.

(2) Magnetizing Technique - Magnetization shall be accomplished by portable prod type electrical contacts pressed against the surface in the area to be examined. To avoid arcing, a remote contro' switch, which may be built into the prod handles shall be provided to permit the current to be turned on after the prods have been properly positioned and to be turned off before they are removed. Braided tips are required for bolting material.

(3)- Prod Spacing - Prod spacing shall be a maximum of 8". Shorter spacing may be used to meet the limitation of geometry of dimensions of the area being examined, or to increase the sensitivity, but prod spacing less than 3" usually is not feasible due to banding of the particles around the prods.

(4) Direction of Magnetization - At least two separate exam-inations shall be carried out on each area with prod: placed so the lines of flux in one examination are approximately perpendicular to the lines of flux in the other.

(5) Magnetizing Current - Direct or rectified magnetizing current shall be used at a minimum of 100 and a maximum of 125 amp per inch of prod spacing for sections 3/4" thick or greater. For sections less than 3/4" thick, amperage shall be 90-110 amp per inch of prod spacing.

(6) Direction of Magnetization - Examinations shall be performed as required to detect the specified discontinuity orientation (s).

Page 11 of 19 (7) Procedure -

Prods are positioned on the surface to be examined and the magnetizing current turned on. The particles are then dusted lightly over the surface. Any excess may be remos-:d with a gentle air stream. The air stream should not disturb or remove lightly held particle patterns. In order to recognize the broad, fuzzy, lightly , held patterns produced by subsurface discontinuities, it is essential to observe carefully the formation of indications while the particles are being applied, and also while any excess is being removed. Proper lighting will facilitate observation of these patterns. Indications of discontinuities shall be noted. The current is then turned off and the prods repositioned 'for the second examination of the area.

(8) Examination Coverage - Examinations shall be conducted with sufficient overlap to assure 100% coverage at the establishe6 test sensitivity.

8.8.2 Coil Method and Procedure (1) Examination Medium - Either dry or wet particles may be used as the examination medium.

(2) Magnetizing Technique - Magnetization is accomplished by passing current through a multiturn coil looped through or around the part, or section of the part, to be examined. This produces a magnetic field parallel to the axis of the coil.

(3) l.iagnetizing Current - For encircling coils, direct or rectified current at 35,000 ampere-turns, divided by the sum of 2 plus the length-over-diameter ratio of the test part shall be used for magnetization. For example, a part 10" long x 2" diameter has an L/D ratio of 5. Therefore, 35,000/(2 + 5) = 5,000 ampereturns; if 5-turn is used, the amperage coil required is 5,000/5 or 1,000.

(a) This formula provides adequate field strength for parts with an L/D ratio greater than or equal to 4. For ratios down to 2 and for smaller parts magnetized in a larger, fixed-size coil, the formula shall be 45,000 ampere-

. turns divided by the length-over diameter ratio. For 1654 057

Page 12 of 19 L/D ratios less than 2, alternate magnetizing methods shall be used. When the magnetizing coil is made of cable wound around the test part, the coils' turns shall be closely spaced. The effective field extends for about 6" on either side of the coll; longer parts shall be magnetized in sections.

(b) For through-coils, the arnperage specified in 8.8.3(3) divided by the number of turns shall be used.

(c) Examinations shall be performed as re the specified discontinuity orientation (s) quired to detect (4) Procedure - After the means of magnetization have been brought into the proper relationship with the surface to be examined, the magnetizing current shall be turned on. The particles are then dusted lightly over the surface. Any excess may be removed with a gentle air stream. The air stream should not disturb or remove lightly held particle patterns. In order to recognize the broad, fuzzy, lightly held patterns produced by subsurface discontinuities, it is essential to observe carefully the formation of indications while the particles are being applied, and also while any excess is being removed. Proper lighting will facilitate observation of these patterns. If wet particles are to be used, they shall be applied typically by spraying, but other appropriate means may be employed. Indications of discontinuities shall be noted, and the second examination of the area is made in accordance with 8.8.2(3) (c) above.

8.8.3 Direct Contact Method and Procedure (1) Examination Medium - Either dry or wet particles may be used as the examination medium.

(2) Magnetizing Technique - Magnetization is accomplished by passing current end-to-end through the part to be tested, which produces a " circular" magnetic field perpendicular to the current flow through the part.

(3) Magnetizing Current - Direct or rectified current shall be used at 700 to 900 amp per inch of part for diameters up to 5",500 to 700 amp per inch of part with diameters 5" to 10", and 300 to 500 amp per inch of part with diameters greater than 10".
