Ultrasonic Metal Testing Essay Example for Free

Ultrasonic Metal Testing tryUltrasonic scrutiny refers to the use of sound energy of high frequency to conduct examinations and make measurements ( elemental Principles of Ultrasonic Testing). This form of inspection may be applied in the detection and military rank of surface flaws measurement of dimensions and classification of materials among other things (Basic Principles of Ultrasonic Testing). It was in the grade 1928 that a famous Soviet scientist by the name of Sergei Y. Sokolov proposed and demonstrated at the V. I. Ulvanov Electrotechnical Institute a through-transmission technique for sight flaws in metals (Early register of Metal Flaw Detectors). Although necessary technology was nonexistent at the time, Sokolov proposed that this technique could be applied in the detection of irregularities in solids. In Germany during the early 1930s, Sokolovs proposal was taken bad enough to begin extensive experimentation on the detection of flaws in metals. O Muhlhauser, in the year 1933, patented a method for the transmission of ultrasonic energy into the solid or metal world tested. This system allowed ultrasonic energy to examine the solid or metal using two transducers (Early History of Metal Flaw Detectors).Ultrasonic metal testing has been useful in industrial applications since the 1940s. Based on the laws of physics governing the spread of sound waves of high frequencies through solids, ultrasonic metal testing helps in the detection of cracks that may be hidden, in addition to porosity, voids and other kinds of internal discontinuities in metals (General ingress to Ultrasonic Testing). Ceramics, plastics, and composites may be similarly tested using ultrasonic systems. Ultrasonic testing also allows easy measurement of thickness as well analysis of material properties.Most importantly, ultrasonic metal testing is entirely safe and nondestructive (General conception to Ultrasonic Testing).ReferencesBasic Principles of Ultrasonic Testing.
