B. GENERAL INTRODUCTION OF THE EMAT TECHNOLOGY

The ultrasonic flaw detection method is based on well-known physical principles. The specific

of the current proposal is applying a very modern and sophisticated technology based on so

called EMAT – non-contact ultrasonic probes. These devices allow one to generate and

receive ultrasonic waves without a coupling liquid, so that no water is needed for ultrasonic

inspection.

1. Physical Basis of Generating/ Receiving Ultrasonic Waves Normal to the Surface

Fig. 4 – Principle of generating/receiving of shears waves with EMAT. Waves are generated exactly normal to the surface

In some cases, EMAT probe is the best or even the only instrument to test metal products for

internal imperfections. The EMAT transforms electromagnetic energy into the energy of

elastic waves and (after interaction with borders of the material and/or defects in it) performs

inverse transformation.

This double transformation is carried out in order to detect defects in a very reliable and

intelligent way.

The active element of the EMAT intended for detection of laminations and wall thickness

measurement is an electrical coil having a special “butterfly” shape (optimal parameters of

these kind of coils are found and patented by Nordinkraft). An example of such coil is

represented below:


6

Fig. 5 – Example of a “Butterfly” coil: the perfect device for transmitting and receiving of

ultrasonic waves normal to the surface of the material to be tested.

A pulse of current in the coil induces the respective eddy current of the similar shape in the

test object’s surface. Because of the well-known physical phenomena (so called “Lorentz

interaction”) some part of the electromagnetic energy is transformed into elastic polarized

shear waves. These waves propagate into the material normal to its surface and reflect from

its surfaces and/or imperfections. Imperfections can be successfully detected if they not

reflect, but scatter or attenuate the ultrasonic waves.

A “Butterfly” coil as well as O – shape coil and Zigzag coil are the basic elements of the EMAT

probe for detecting laminations and /or cracks in plates.

One of the key advantages of the EMAT is that the ultrasonic waves are generated into

material and received from it without its direct contact with the material; no need in Couplant!

The second important advantage of the EMAT is that for the relevant configurations

ultrasound it generates always normal to the material surface so that the direction of

transmitting of ultrasonic waves is always perpendicular to its surface: regardless the probe

inclination or test object geometry change

Width of the active

zone

Length of the active zone

Fig. 6 – Inclination of the EMAT

EMAT is the most effective instrument to transmit and receive share waves, allowing one to

get the best detectability and resolution. This factor assumes one more advantage of the

EMAT- technology.

2. Physical Basis of Surface/Subsurface Defects Detection

An active element of the EMAT is an electrical coil of a special “zigzag” shape. Pulse of

current through the coil induces a respective eddy current of a similar shape in the bar

surface. Because of a well-known physical phenomena (so called “Lorentz interaction”) and

a special eddy current distribution some part of the eddy current energy is being transformed

into a power of the elastic wave (so called Rayleigh wave). This wave propagates along the

surface around the bar/billet cross section (see figure below) being reflected by surface/sub-

surface defects.

An important specific of a Rayleigh wave is that its energy propagates along the bar/billet

surface, following its shape curvatures. Surface and subsurface defects reflect the Rayleigh

wave back to the EMAT initial position. Elastic vibrations of surface at the presents of a

magnetic field induce eddy current in the bar/billet surface, being detected by the same coil

of the EMAT.

Calibration is fully automatic. Bottom signals (internal defects) and round passed signals (external defects) will be used for the automatic calibration of the UT-equipment;

Equipment is very simple for practical use. It DOES NOT require good and qualified service team;

Ultrasonic flaw detection equipment has the highest degree of automation level. It can automatically assess the defects in accordance with the adjusted sensitivity;

UTE reserves possibility to manually modify or upgrade the ultrasonic flaw detection or evaluation criteria. Operator is able to add new flaw evaluation rules into the operation list;

All the electronics, automatics and PC-related elements have self-diagnosis functions and automatic power-off protection. Diagnosis includes the diagnosis of system hardware, the communications testing for each unit, each channel in the probes, as well as testing the ability of the flaw inspection. At the same time, the system is able to save ultrasonic flaw detection equipment operating parameters and can set the equipment automatically based on flaw detection requirements;

3.2 Supporting Frame (Pedestal) Supporting Frame is installed in the testing area transversally to bars transportation direction.

Supporting is equipped with the Rail Track, and auxiliary equipment (including flexible track for cables and air hoses) enabling movement of the Test Unit from service to calibration or working position. In addition such units as Power Distribution Cabinet, Control Computing Unit and Components of Test Electronics are installed on the Supporting Frame.

Fig. 13 – Test Unit


16

3.4 EMAT (Electromagnetic-Acoustic Transducer) EMAT-probe is a very important component of the equipment. EMAT generates ultrasound

and receives ultrasonic waves in/from material by means of electromagnetic-acoustic

transformation. Transmitted ultrasonic waves propagate through the material, reflect from the

opposite surface or from the defects, and come back to the probe. In the receiving mode the

EMAT transforms acoustic vibration of the TO surface into electrical signals.

Test Unit is equipped with tree multichannel probes.

Design of the EMAT

EMAT probes for the current application of rolled wire testing are the innovative high-tech

products; they meet the highest technical standards.

Each EMAT includes two separate system:

Internal Defects Detection System (IDDS); Surface Defects Detection System (SDDS).

Respective resources of IDDS and SDDS are located in the same probe case. Design of

probes is the Seller‘s intellectual property.

Fig. 14 – Example of the EMAT produced by Nordinkraft

Main specifics of our EMATs:

The case of probe is made of high quality stainless steel, resistant to rusting and mechanical scratching;

Working surface of the probe is protected by a resistible plastic or ceramic. Such materials are extremely effective for protection of the working surface and extension of probe life-time; nevertheless, the probes don’t directly contact with the wire – special protective inserts from hard iron are applied;

Special double-shielded elastic cables provide a perfect noise protection and prevent mechanical damages.

26

4. Description of the test process

1) Before the testing starts operator should adjust the main testing parameters:

Thresholds Gates positions Test object part length Number of eject parts Distance between last EMAT section and defect part eject point

Test Unit is in the initial position.

2) When the bar/wire is supplied to the test area, operator moves the Test Unit to the

working position, brings the EMAT to bar/wire surface, and then presses “Start” button on

the main software window;

3) After the systems reset the coordinate, it adjusts the current coordinate as zero and

switch “on” initial pulses;

4) Tested wire continues its movement; system starts the evaluation process.

If during testing a defect is found the system sends eject signal for every rejected part when it reaches the sorting point;

If during testing the system receives “Stop” signal, the system pauses (switch off initial pulses) until the signal is active.

5) When the testing is finished, operator presses the “Stop” button on the main software

window. System switches “off” the initial pulses and stopes counting the coordinate;

6) Operator retracts the EMATs from the tested wire; system is ready for the next testing;
