Page 4:4Principle of generating/receiving of shears waves with EMAT.Waves are generated exactly normal to the surface.The ultrasonic flaw detection method is based on well-known physical principles. The specific of the currentproposal is applying a very modern and sophisticatedtechnology based on so called EMAT – non-contactultrasonic probes. These devices allow one to generateand receive ultrasonic waves without coupling, so that nowater is needed for ultrasonic inspection.General introduction of the EMAT technologyEMAT probe is the best instrument to test metal productsfor internal imperfections. The EMAT transformselectromagnetic energy into the energy of elastic wavesand (after interaction with borders of the material and/ordefects in it) performs inverse transformation.This double transformation is carried out in order to detectdefects in a very reliable and intelligent way.The active element of the EMAT intended for detectionof laminations and wall thickness measurement is anelectrical coil having a special “butterfly” shape (optimalparameters of these kind of coils are found and patentedby Nordinkraft). An example of such coil is representedbelow:Example of a “Butterfly” coil: the perfect device for transmitting andreceiving of ultrasonic waves normal to the surface of the material to betested.A pulse of current in the coil induces the respective eddycurrent 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 electromagneticenergy is transformed into elastic polarized shear waves.These waves propagate into the material normal to itssurface and reflect from its surfaces and/or imperfections.A “Butterfly” coil is the basic element of the EMAT probefor detecting laminations in plates.One of the key advantages of the EMAT is that theultrasonic waves are generated into material and receivedfrom it without its direct contact with the material; no needin couplant!The second important advantage of the EMAT is thatultrasound is generated always normal to the materialsurface so that the direction of transmitting of ultrasonicwaves is always perpendicular to its surface: regardlessthe probe inclination or test object geometry change (seethe diagram in Fig. below):Inclination of the EMATEMAT is the most effective instrument to transmit andreceive share waves, allowing one to get the bestdetectability and resolution. This factor assumes onemore advantage of the EMAT-technology.

Page 5:5Detecting of Defects by means of SV-share WavesThe physical principle of defect detection is based on receiving and analysis of waves, reflected from the cracks on atop and bottom surface of the sample. These waves are being transform by EMAT to weak electrical signals, which afteramplification and processing are displayed in the A–scan.Detection of crack on the bottom surfacePrinciple of ultrasonic SV-waves generation with EMATFor cracks on the bottom surface, signal in the A-scan is correspond with the wave witch propagates from point A,reflects at point B and than being received at A.It is very easy to keep the angle β stable with the EMAT:the beam angle do not depend on the probe inclinationand test object dimensions or shape. On the contrary, apiezo probe will not work in our case: even a little ultrasonicbeam inclination or change of the tube shape (that ispractically inevitable with piezo probes) will immediatelyinfluence the beam angle.This phenomenon allows one to extend distances foroptimal detection of defects located on both sides of thewall. This is a very important feature of the EMAT as itsubstantially increases an industrial reliability of the testresults. This is a great advantage of the EMAT-technology.Thus, SV- waves transmitted by the EMATare an extremelyeffective instrument to detect internal and external defectsin flat samples, tubes, pipes, cylinders, and etc.Inclination of the EMAT

Page 6:6Equipment CompositionBasic set of SonaFlex equipment consist of the followingmain components:Test Electronics Unit;Electromagnetic Acoustic Transducer (EMAT);Control Computing Unit with installed UT Software.Detecting of Surface Defect by Means of EMATBased on the physical principle described above, EMAT probes are developed for ultrasonic inspection of surface orsubsurface of materials. EMAT transforms electromagnetic energy into the energy of surface elastic waves and (afterinteracting with defects) performs the inverse transformation. This double transformation is carried out in order to detectsurface and subsurface defects in a very reliable and intelligent way without mechanical rotation of probes.Generation of Surface waves by means of EMATPrinciple of surface defects detection by EMATSonaFlex composition

Generator GE generates initial tonebursts (violet line in the diagram) in the coil of the probe.Ultrasonic waves are transmitted into the pipe.Ultrasonic waves are reflected by walls borders andreceived by the same coil the probe.The signals are pre-amplified by the preamplifiers PA andgo to the PR8В unit for the analog processing. ADC-7 unitcontrols the gain of the PR8D board. It can be controlledautomatically.After the final amplification, signals are entering the ADC-7 board for being digitalized and processed.Signals processing contains digital filtering and measuringof the relevant informative parameters.Digital signal processing includes also up to 64 cycles ofcoherent accumulation (averaging), detection, filtration,gating and assessment of received signals’ peak values.Data-flow from ADC-7 is transmitted to Computing Unit viathe Ethernet (green line in diagram). This data from ADC-7 is entering Computing Unit for secondary processing,storing and representing.

Page 8:8Design of the EMATEMAT probe for research/monitoring applications have a common appearance but different internal organization – shapeand dimensions of active element as well as configuration of permanent magnet should be specified for generation ofdifferent type of Ultrasonic Waves.EMAT probes for research/monitoring applicationsEMAT (electromagnetic-acoustic transducer)EMAT-probe is a very important component of the equipment. EMAT generates ultrasonic and receives ultrasonic wavesin the material by means of the electromagnetic-acoustic transformation. Transmitted ultrasonic waves propagatethrough the material, reflect from the opposite surface, and come back to the probe. In the receiving mode the EMATtransforms acoustical vibration of the TO surface into electrical signals.Typical probes for Lab applications are shown on the figure below:EMAT for wall thickness measurementand lamination detection;EMAT for angular ultrasound excitation; EMAT for surface waves generation/receiving
