There are many ways in which we can strive to produce an excellent report document detailing a guided wave ultrasonic testing inspection. The Report Manager within Wavescan software, used in conjunction with the Teletest Focus+™ instrument, has been designed with this in mind. Incorporating photographs and isometric drawings are helpful and can be useful to explain things that would be very ...

Aug 03, 2019 · Guided Wave Ultrasonic Testing (GWUT) or Long Range Ultrasonic Testing (LRUT) is one of latest methods in the field of non-destructive evaluation. The method employs mechanical stress waves that propagate along an elongated structure while guided by its boundaries. This allows the waves to travel a long distance with 2 little loss in energy.

Over the last decade, commercialization of Guided Wave Ultrasonic Testing (also referred to as Long Range UT) has provided industry with a powerful new technique for ascertaining the integrity of piping systems. The major advantage of the technique is it's capability to screen inaccessible piping over long distances from a single exposed location.

The frequency used in the inspection depends on the thickness of the structure, but guided wave testing typically uses ultrasonic frequencies in the range of 10 kHz to several MHz. Higher frequencies can be used in some cases, but detection range is significantly reduced.

Despite technical advancement and wide industrial application, long-range ultrasonic testing (LRUT) has several bottlenecks, which restrict its abilities and complicate the data interpretation. Particularly, these are related to simultaneous …

The prototype of a guided ultrasonic wave array for the structural integrity monitoring of large, plate-like structures has been designed, built, and tested. The development of suitably small transducers for the excitation and measurement of the first antisymmetric Lamb wave mode A(0) is described. ... Practical long range guided wave testing ...

Diagnostic ultrasound is a non-invasive diagnostic technique used to image inside the body. Ultrasound probes, called transducers, produce sound waves that have frequencies above the threshold of human hearing (above 20KHz), but most transducers in current use operate at much higher frequencies (in the megahertz (MHz) range).

Ultrasonic guided waves have been widely applied to the long-range inspection of straight piping. The interpretation of the guided wave ultrasonic testing data beyond welds and elbows is challenging because there are many wave modes with different sound velocity. One of the key techniques to examine the beam path of each guided wave mode is the ...

HOW IT IS USED Ultrasonic waves can be used in three regimes depending on inspection distance:- • Short range (<< 1 m) • Medium range (up to about 5 m) • Long range (up to around 100 m) Wave form of three layer structure Aluminum-Adhesive-Aluminum, (a) Non-Corroded Region, (b) Corroded Region at the Bottom, (c) Corroded Region at the Top:

containing a piezoelectric substance, e.g., a quartz-crystal oscillator that converts high-frequency electric current into vibrating ultrasonic waves. Ultrasonics has found wide industrial use. For nondestructive testing an object is irradiated with ultrasonic waves; variation in velocity or echo of the transmitted waves indicates a flaw.

9 Rock Bolt s Integrity Testing Ultrasonic Guided Waves: Principle: A short duration Gaussian windowed sine burst is used to excite a guided wave in the bolt from the free end. The wave is then reflected from the other end and from any major defects. From the reflection arrival time and knowledge of the wave velocity dispersion curves, the positions of the defects or the bolt length can be ...
