Ultrasonic Testing is Widely Used in Industries Applications

When there are defects in metal products, like bubble, cracks, separation layer, or bubble in defects or mixed with bubbles, people will use ultrasonic crack detection tools to find out. The basic principle of ultrasonic detection is when the ultrasonic wave is transmitted to the surface of the metal and defects, it will be all reflected or partial reflected. The reflected ultrasonic waves were to be received by the detectors’ pin and than will be processed by the detector. In the display screen, there will be different shape and different heights and distance of the waves. Judging from these wavelength changing features, you can check the depth, position and shape of the defects.

From wikipedia introduction, Ultrasonic testing, also called UT, is a family of non-destructive testing techniques based on the propagation of ultrasonic waves in the object or material tested. In most common ultrasonic testing applications, very short ultrasonic pulse-waves with center frequencies ranging from 0.1-15 MHz, and occasionally up to 50 MHz, are transmitted into materials to detect internal flaws or to characterize materials. A common example is ultrasonic thickness measurement, which tests the thickness of the test object, for example, to monitor pipework corrosion.

For inspection that vision inspection or video measurement can not do, ultrasonic testing will work. In industry application, ultrasonic testing is mostly used for testing plastics, metals, composites, and ceramic materials. The only industrial materials that are really not suitable are papers and woods, which we usually use laser or vision instead. The most importance industries buying ultrasonic testing service are the oil and petroleum industries, where welded pipes, tubes and tanks are often tested.
