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 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. Ultrasonic testing is often performed on steel and other metals and alloys, though it can also be used on concrete, wood and composites, albeit with less resolution.
Portable Metal Spectrometer is used for inspection, quality control, and alloy identification. Many times this is also called as metal analyzer. In Market Bench top and Portable both variants are available. In bench top most popular is OES Spectrometer and in case of Hand Held Portable Spectrometer X-Ray and LIBS Spectrometer Both are available. It gives result in 1sec. without Argon gas.
