ULTRASONIC INSPECTION
ULTRASONIC INSPECTION
Ultrasonic inspection (UT) is a non-destructive test method that utilizes sound waves to detect cracks and defects in parts and materials. It can also be used to determine a material’s thickness, such as measuring the wall thickness of a pipe. Because of the portability of the equipment and variety of methods available, ultrasonic testing allows for inspection of parts that are large, irregularly shaped, or unable to be transported.
Ultrasonic inspection relies on electronic transducers that transmit high-frequency sound waves to a material. These sound waves bounce back crystal-clear images, which reveal key characteristics about a material’s properties. The images created by ultrasonic testing can indicate cracks, weld grooves and fractures, as well as indicate material thickness and outline moving components.
Because this method has higher power potential than other non-destructive test types, ultrasonic inspection can produce images that are more clearly defined than other methods, and indicate characteristics deeper than surface level. Depending upon the test requirements, parts can be tested by immersion (in-lab testing) or contact (portable/in-air) inspection.
Ultrasonic Flaw - Crack Detection
Ultrasonic Testing or Ultrasonic Flaw Detection is a type of non-destructive Testing that employs high-frequency ultrasound waves to perform inspections and measurements. Ultrasonic inspection is often used to discover and evaluate flaws, measure dimensions, characterize materials, and more.
Sound waves with a frequency greater than 20 kHz and a 1.9 cm or less wavelength at atmospheric pressure are known as ultrasound waves. In simpler words, ultrasounds are sound waves having frequencies greater than the human hearing limit.
Ultrasonic Flaw Detection uses these ultrasonic sound waves to detect flaws inside a solid metal or concrete object without causing any damage to its original structure.
Ultrasonic Thickness Measurement and Testing
An Ultrasonic Thickness Testing works by precisely measuring how long it takes for a sound pulse that has been generated by a small probe called an ultrasonic transducer to travel through a test piece and reflect back from the inside surface or far wall.
Ultrasonic thickness testing requires knowing the specific application required to have the accurate result, there are different aspects that require consideration when selecting the right ultrasonic thickness measurement methods, Whether inspections will take place on-line or in a quality control (QC) laboratory through coating measurement small wall thickness values with accuracy and high resolutions.conducted by competence personnel.
Ultrasonic Bond Testing
Reliable bonds are essential to the integrity of composite structures throughout their service life. Therefore, Ultrasonic Inspection methods have been developed to assess bonding quality during maintenance. This application developed to improve the reliability of inspection on composite meterial.
