The penetrant methodof non-destructive testing is based
on capillary penetration of indicator liquid (penetrant) into thesurface defects (cracks, pores, etc.). After intermediate
cleaning and subsequent drying, a developer is applied as a
thin, white layer onto the surface to be inspected. Thedeveloper pulls the penetrant out of the surface defects and
makes them visible as coloured, linear or rounded indications.
Documentation is possible by means of adhesive films,photographs or video techniques.
Penetrant testing is reliable in detecting the defects with a
width down to the range of m.
Penetrant inspection can detect surface defects accuratelyand easily independent of types, materials and surface
configuration of the objects to be tested. Other methods ofnon destructive testing can be applied only with restrictions.Necessary condition: defects must be open to surface.
Capillary systems have been also used for the leak testing.

NORD-TEST PENETRANT SYSTEM
The NORD-TEST penetrant system iswidely applied for parts testing in
engineering and automobile industries, ship
and boiler building, welding, etc. in atemperature range from 5C to +50C.
In order to assure the proper sensitivity
while testing at low temperature (from -5 to + 10 ) it is necessary to increase
the penetration time according to the
requirements of DIN EN ISO 3452, Part 2
and EN 571, Part 1.
For testing at higher temperature (from+65 to + 175 ) the Super-Chek
penetrant system has been specially developed.
The NORD-TESTpenetrant system was tested andapproved in accordance with DIN EN ISO 3452-2,
EN 571, KWU and meets the requirements of
Lloyd's Register of Shipping, Bureau Veritas,Bureau Central Hollandais, Germanischer Lloyd,
MIL-I-25135/QPL-25135, AMS 2644, ASME Boiler
and Pressure Vessel, ASTM E-165, ASTM-E1417.
The low content of sulfur and halogens wasascertained and confirmed according to ASTM E
165-02 and ASTM D 516-02, as well as to
requirements of KWU and DIN EN ISO 3452.

STATIONARY FACILITIES FOR PENETRANT TESTING
Stationary devices for fluorescent penetrant testingcorrespond to the specifications of main world standards:MIL-I 25135E, MIL STD 6866, AMS 2644, EN 571-1. All
components meet the European requirements for Health,
Safety and Ergonomics.
The inspection systems are basically made of stainless steeland equipped with first class means for functional control.The devices are designed and manufactured according to
customers performance specifications with regard for
specific inspection tasks and test objects.
Main stages of processing:
1. Pre-clean;2. Wash;
3. Dry to = 1000C;
4. Cool to T = 40;5. Dip in a tank with penetrant
6. Water wash
7. Dip in a tank with emulsifier8. Post water wash;
9. Dry at =60 C;
10. Electrostatic application of powder developer;11. Surface inspection under UV irradiation.
ELECTROSTATIC DEVICES
Electrostatic liquid application
is a high-efficient coating method,
offering decisive advantages overconventional application
techniques in many areas of
industry including penetranttesting.
Due to the electrostatic chargethe penetrant (developer) particles
repel each other to produce an
extremely fine atomization. Theuniform spray jet generates a very
homogeneous material application
with an even coating, resulting in aparticularly high quality finish.
The wrap-around effect results
from a force field between the negatively charged penetrant(developer) particles and the grounded work piece. Both
the front and rear of the work piece can thus be coated at
the same time with enormous savings in material andtime.
To achieve maximum wrap-around and optimumapplication efficiency the electrostatic systems operate at a
very high level of performance.

The magnetic particle testing method(MT) is one of the
most sensitive, reliable and productive NDT-methods forsurface inspection of products from ferromagnetic
materials. The method is based on the attraction of
ferromagnetic particles by force of leakage flux which
appears above surface defects like cracks, laps, lacks offusion, pores after an adequate magnetization. MT can be
used for indication of open surface defects and under
certain conditions for detection of near-surface defects. Ahigher probability of detection is given, when the direction
of a defect is perpendicular to the direction of the applied
magnetic field. The smaller is the angle between the defect
and magnetic field lines, the weaker is the indication.
Microscope imaging of cracks Cracks indication by fluorescent MT method
The magnetic particle testing is a separate processing procedure which consists of following parts: 1.Preparation of the testobjects surfaces for testing; 2. Magnetization of the object; 3. Application of magnetic particle suspension (powder) onto the
test object; 4. Inspection; 5. Demagnetization.
Circular, longitudinal or combined magnetization is used for the magnetic particle testing. There are a lot of magnetization
schemes, some of which are shown below.

HAND MAGNETIZING DEVICES
HAND YOKE ELECTROMAGNETS
With the HANSA series the HELLINGCompany presents a new generation
of hand yoke electromagnets,
which excel by many advantages ascompared with the previous series:
they are more lightweight, handy,
powerful!
An important ergonomic feature ofthis series is the special narrow
handle, which facilitates a fatigue-
free working even for small hands.
The series includes the UM 8, UM 9,UM 10 and UM 15hand yokes. The
UM 8, 9 and 10 hand yokes differ in
dimensions (pole spacing andlength), in weight and in liftingstrength. Optionally the devices can
be fitted with two-limbs flexible legs,
whose lower limbs can be swung inwards and outwards by45. The pole spacing can be hereby increased or decreased
by approximately 60 cm. Due to 45 inclination of the
contact surface the legs fit optimal the geometry of theobject under testing.
The UM 15 hand yoke is providedwith three-limbs flexible legs in
standard execution. Hereby the poles
distance can be set in the range from95 up to 250 mm.
All hand yokes of HANSA series meet
also with flexible legs by maximum
pole spacing the requirements ofgeneral guidelines and standards (EN
ISO 9934-3, ASTM 709 and ASME-
Code, Sect. V). Here a liftingstrength of min. 45 N (4,5 kg) or a
tangential field strength of min. 20
A/cm (EN ISO 9934-3) is required as
operational capability proof.The HANSA hand yokes arecompletely sealed, being fed with
main voltage of 230 Volt and possess
the IP 65 protection class. They can be used (with theexception of UM 8 (60 sec./30% ED) with the maximum
turn-on time of 150 sec. and maximum duty cycle of 50%.
The cable can be uncoupled in order to prevent breaking ofthe connecting bushing.

HAND MAGNETIZING DEVICES
KMU 8/42 CROSS YOKE
The KMU 8/42 Cross Yokerepresents a supplement to the
HANSA Series the new generation of hand yokemagnetizing devices. The KMU 8/42
consists of two alternating current
yokes disposed crosswise with polespacing of 170 mm.
They are fed by 2 equipotent
alternating currents with 90 phase
shift, what results in rotatingmagnetization vector, whose field
strength is equal in all directions.
This magnetization techniqueenables the detection of
discontinuities of every orientation.In practice it means: simultaneous
indication of longitudinal,transversal and oblique cracksin
the course of only one operation.
Therefore the KMU 8/42 Cross Yokeis especially appropriate for
inspection of lengthy welded joints,for example in pipe manufacturing,
tank and pressure vessel building or
ship building. The long-duration dutycycle of up to 60% advantages the
application in these production fields.
The magnetic field is being applied into the part under test
over a short air gap. Thereto the yoke poles are providedwith adjustable castors. The castors
maintain a constant air gap between
the poles and the part surface andenable the yoke to be moved easily.
The assembled Cross Yoke reaches a
tangential field strength of 32 A/cm
and a lifting strength of more than300 N (30.6 kg). Even with the air
gap of 5 mm the tangential field
strength is still 22 A/cm!
The KMU 8/42 Cross Yoke iscompletely sealed, being fed by an
additional transformer with 3 x 42 V
alternating voltage and possesses
the IP 54 protection class. The CrossYoke and the transformer are
coupled with a flexible cable 5 m
long. The transformer meets criteriaof the IP 23 protection class and
requires the primary voltage of 3 x
400 V.

INDUCTIVE UV and WHITE LIGHT LED SOURCES
Inductive UV or White Light LEDSources are used while working with
hand yoke or cross yoke
electromagnets. The networkindependent light sources have been
designed for simultaneous irradiation
(illumination) of the working areaduring testing with fluorescent or
colour magnetic particle powder by
single handed operation only. Theadjustable swivel head ensures the
correct irradiation angle depending ondistance between poles and length of
legs of yoke in order to get an
optimum homogeneous irradiation fieldright in the center of the working area.
The splash protected (IP 65) light
source fit on all hand yokes with a polecross section up to 50 x 50 mm.
The light sources can be fixed quickly andeasily at the yoke leg and fastened with
two plastic screws.
When switching on the yoke i.e. during
magnetizing, post-magnetizing andexamination cycles the unit is being fed
by inductive current and illuminates or
irradiates the working area. Thereforeneither battery nor mains supply is
needed.
The light sources have proved themselves
especially in testing under restricted spaceconditions, on construction sites and
improvised test places, where only limitedpossibilities for auxiliary instrument usingare available.

That is why the NR 01 Cross Yoke will especially do for inspection ob tube ends, tooth
gears and different cylinder parts. The NR 01 Cross Yoke is designed for a long-durationduty cycle of up to 90%.
The NR 01 Cross Yoke is completely sealed, being fed by an additional transformer with3 x 42 V alternating voltage and possesses the IP 54 protection class.
CROSS SHAPED COIL
The cross shaped coil is being used for non-contact magnetization of bars, billets, ingots or
cylindrical parts. It is being fed by two equipotent alternating currents that are dephased
by 90, generating a rotating magnetizing vector on the horizontal plane and therebyindicating surface cracks of any orientation. By rotating the part within the coil the whole
surface can be tested (except for end faces).
HETT DEMAGNETIZING TUNNELS
The demagnetization effect of the AC demagnetizing tunnels is based on the principle ofsubjecting the part to a reversing and decreasing magnetic field. This can be accomplished
by pulling a part out and away from a coil with AC passing through it.
The AC magnetic field penetration at 50 Hz frequency is about 2 mm (on steel). In order to
increase the penetration depth an additional low-frequency generator with 16Hz shouldbe used.

MOBILE MAGNETIZING DEVICES
HEAVY CURRENT GENERATORS
HELLMAG-series mobile magnetizing devices are heavy currentgenerators designed for current flow and field flow
magnetisation, coil magnetization, pulse magnetization as wellas for demagnetization.
During current flow magnetization the contact electrodes(see P.35) are being attached to the edges of the test
piece, thus the part itself becomes a current-carrying
conductor. The circular magnetic field generated aroundthe part allows the detection of longitudinal cracks
between the contact poles. This technique makes it also
possible to find the defects which are located at an angle ofup to 60 degrees off the axial line. In order to avoid
overheating, burns or electric arcs in the contact area it is
important to ensure proper current transition by using copperbraid pads or melt-off electrodes.
When using HELLMAG equipment for field flow magnetization,power cables are being used as inner or outer conductors or as
a cable coil respectively. Inner conductor: this way ofmagnetizing is used for testing ring shaped work pieces.
Thereto the power cable should be put through the center hole
(bore) of the work piece. Thereby cracks that are locatedmainly parallel to the conductor are being detected. Outer
conductor: this way of magnetizing is often used for testing
weld seams. Here one or more power cables should be
positioned parallel to the weld. Thereby longitudinal cracks are
being detected. In order to avoid field compensations, the
current reverse flow cable is to be located as far away aspossible from the magnetizing cable. Cable coils: while coil
magnetizing, a current-carrying conductor should be wound
like a coil with an appropriate number of windings. Afterenergizing the coil, circular magnetic fields will be generated
around each coil winding. In the center of the coil thesemagnetic fields add on to a general longitudinal magnetic field,
therefore cracks located across the magnetic field i.e.
transversal cracks are being indicated.
HELLMAG devices can be combined with a variety of testing
equipment such as the chain testing device, closed or hingedcoils, trapezoidal coils for testing of railway wheels (see also
pages 35 to 36).
The testing current can be infinitely adjusted through a foot-
switch operated potentiometer (when the magnetizing circuit
is closed). A selector switch changes between the differentmodes: Magnetizing Demagnetizing Pulse. The devices are
equipped with 230 V plug sockets for connecting additional
equipment such as an UV lamp or a suspension pump.
