Monitoring with a high frequency (UT) uses high-frequency ultrasonic waves to detect cracks on the surface and internal defects. Measure the thickness of the object, and define criteria for accepting and rejecting object that checks from the basis of the reference standard or code. A fault detection method for fast and accurate monitoring to assess the integrity within the workpiece. Sound waves to infiltrate deep into the object that performs a search for the fault cracked cracks split into layers. Fissure of welding and other discontinuityTo check with shear wave (wave shear) checking with the method A-scan will pass the wave ultra sonic that corner into the calibration verification material until you find a bug, then the energy will be reflected back to the transceiver (transducer), the display will show the distance the wave travels to the imperfections in the crease and the strength of the signal returned.To verify how a high majority of UT used to guarantee the integrity of critical equipment or welding structure, but can also be used to detect, monitor and/or tell me the amount of fault occurs in the area. Monitoring is usually used after welding. In addition, if the welding requirements. Welding, grinding and welding of the new design will be. To verify how UT has advantages over the method RT is that there is no risk from radiation and does not interfere with the work in the surrounding area.There is a technique to determine the highest frequency of modern method and a variety of different technologies, such as Phased Array (amplitude, high frequency risk phase arrangement) and TOFD (diffraction of sound waves) DACON highly skilled in techniques to monitor all from UT thickness measurement through checking for corrosion at strut area.
