The transmission of high-frequency sound waves into a material to detect imperfections or to locate changes in material properties.(Course Material/cc_ut_index.htm)(Course Material/NDTIntro/cc_intro001.htm)(Course Material/Ultrasonics/Introduction/presentstate.htm)
In this test method, reflected ultrasonic sound wave signals can be used to determine and locate defects such as laminations in the wall of pipe, as well as measure the remaining wall thickness. Ultrasonic testing is a non-destructive inspection method frequently used in the pipeline industry. It consists of an instrument with a probe that generates high-frequency sound waves and detects their reflection off the pipe inner surface.
A method of nondestructive testing of solid metal for internal flaws utilizing high frequency sound waves.
A non-destructive inspection method using sound waves for surface or sub-surface welding or base material testing. Ultrasonics can also be used for thickness testing.
A nondestructive test applied to materials for the purpose of locating internal flaws or structural discontinuities by the use of high-frequency reflection or attenuation (ultrasonic beam).
testing procedure used to determine the size and location of defects within a metal product. The process uses short bursts of acoustic energy (sound waves) in the ultrasonic range and reads back the reflections of these bursts to identify any defects.
A non-destructive testing method, which transmits a beam of high frequency sound into the tube and listens for echoes returned by discontinuities.
A nondestructive method of testing metal for flaws based on the fact that ultrasonic waves are reflected and refracted at the boundaries of a solid medium. Ultrasonic testing is used to detect flaws in materials.
In ultrasonic testing, ultrasonic very short pulse-waves of frequencies ranging from 0.5-15 MHz and occasionally up to 50 MHz are used to detect flaws or characterize materials. It is also commonly used to determine the thickness of the test object - monitoring pipework corrosion being a good example.
