Electromagnetic-acoustic Transduction (EMAT)


The technology enables non-contact generation of acoustic waves of different types with different polarization in the test object. Modern element base allows us to create flaw detectors and thickness gauges that are based on EMAT and operate across the operating gap of up to 10 mm. In other words, there can be paint, plastic, dirt, air and other non-conductive material with a thickness up to 10 mm between the test object surface and the transducer.

Eddy Current Non-destructive Testing

11-1-2
The technology provides non-contact and quick testing of the metal objects. Modern devices based on eddy current technology are able to detect and estimate the size of surface and sub-surface flaws, under certain conditions detect flaws located on the inside of the test object, measure the gap between the transducer and the test object, measure the thickness of the test object, including objects made of steel.

Magnetic Non-destructive Testing

prof-2
Magnetic non-destructive testing is based on analysis of dispersion fields generated during test object magnetization in the area of a flaw. The technology allows performing instant diagnosis of ferromagnetic test objects with high efficiency. Tubes of small and large diameters, vertical steel tanks, rods and flat steel can be tested using the technology. Operating principle of magnetic flaw detectors for testing pipelines is based on the technology. The technology is non-contact and does not require advance surface preparation.

Laser Profilometry


Laser profilometry allows detecting surface flaws of the test object, as well as making accurate measurements of flaw dimensions. The technology is non-contact. The distance between the optical system and the test object surface can be dozens of centimetres. In particular, the technology can be used for automatic welded seam quality control that reveals surface flaws.
