In ultrasonic testing, high-frequency sound waves are transmitted into a material to detect imperfections or changes in material properties in the surface or subsurface. The sound waves travel through the materials with some attenuation of energy and are reflected at interfaces. The reflected beam is detected and analyzed to define the presence and location of flaws.
Cracks, laminations, shrinkage, cavities, bursts, flakes, pores, bonding faults and other discontinuities that can act as metal-gas interfaces can be easily detected. Inclusions and other imperfections in the metal being inspected can also detected by causing partial reflection or scattering of the ultrasonic waves, or by producing some other detectable effect on the ultrasonic waves.
Ultrasound testing has many uses such as thickness testing (UTT), Conventional (UT) and the most advanced testing is Ultrasound Phased Array (UTPA). Phased Array is widely used for non-destructive testing (NDT) in several industrial sectors, such as construction, pipelines, and power generation. This method is used to test or interrogate a large volume of material. A conventional probe must be physically scanned (moved or turned) to sweep the beam through the area of interest. In contrast, the beam from a phased array probe can be focused and swept electronically without moving the probe. The beam is controllable because a phased array probe is made up of multiple small elements, each of which can be pulsed individually at a computer-calculated timing. The term phased refers to the timing, and the term array refers to the multiple elements. Contact Red Deer Ironworks Inc. for ultrasonic testing in Texas, Colorado and Red Deer.
