Many techniques have been developed to allow full volumetric inspection of a large range of components made from a wide variety of materials. Ultrasonic Testing of Materials book. Ceramics, plastics, composites and concrete can also be successfully inspected but with reduced resolution, since the attenuation in these materials is higher. A transducer (1) is connected to the oscillator (10) for applying an ultrasonic signal to the material and for receiving an echo signal back from the material. Abstract: An ultrasonic apparatus for testing a material comprises an oscillator (10) which generates a selected frequency in the ultrasonic range. In industrial applications, ultrasonic testing is widely used on metals, plastics, composites, and ceramics. Our immersion UT systems are set up for high-speed inspection of tubing, pipe and round bar stock of material diameters from 0.125 inch to 6.625 inches with a maximum weight of 1,000 pounds and lengths up to 70 feet. To get more specific, ultrasonic testing is done in materials to determine the presence of defects by measuring their thickness using high-frequency sound waves (typically 500kHz-20Mhz). If there are . If there are no complaints after the test, the component can continue to be used. Ultrasonic testing (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 UT applications, very short. It is employed in a variety of industries, including the manufacturing, aerospace, automotive, and other transportation sectors, as well as the construction of steel and aluminium structures. Ultrasonic inspection may also be utilized to measure the thickness of materials and to characterize the properties of various materials. Ultrasonic testing is also used in oncology and other medical fields for diagnostic testing. There are several non-destructive examination (NDE) ultrasonic techniques. UT is ideally used for inspection of dense, crystalline structures such as metals. The ultrasonic principle is based on the fact that solid materials are good conduc-tors of sound waves. The only common engineering materials that are not suitable for ultrasonic testing with conventional equipment are wood and paper products.
