The first efforts to use ultrasonic testing to detect flaws in solid material occurred in the 1930s. On May 27, 1940, U.S. researcher Dr. Floyd Firestone of the University of Michigan applies for a U.S. invention patent for the first practical ultrasonic testing method. The patent is granted on April 21, 1942 as U.S. Patent No. 2,280,226, titled "Flaw Detecting Device and Measuring Instrument". Extracts from the first two paragraphs of the patent for this entirely new nondestructive testing … WebUltrasonic testing methods use sound waves to find defects and measure thickness. Ultrasonic Testing (UT) is also often called Ultrasonic Thickness Measurement (UTM), Ultrasonic Thickness Testing (UTT), or Sonic Testing (ST). It is most commonly used on metal, because metal conducts sound waves in a manner that supports this kind of …
