Shear wave testing, also known as angle beam inspection, is an ultrasonic testing technique used primarily for weld inspections. A probe consisting of an ultrasonic transducer coupled with a plastic or epoxy wedge introduces an ultrasonic beam at an angle into a test area. O&G-UT-PTP8 Manual Ultrasonic Shear Wave ASME Weld Quality Examination (PDF) Re-examination Policy.

Twin crystal shear wave transducers hold two crystals mounted at inward angles that provide improved near-surface resolution and superior signal-to-noise ratio. Ideal for inspecting thin materials for small flaws, occurring directly under the surface.

SHEAR WAVE/PHASED ARRAY UT The two most commonly used types of sound waves used in industrial inspections are the compression (longitudinal) wave and the shear (transverse) wave, as The angle-beam (Shear Wave) technique is used for testing sheet, plate, pipe, & welds.

Shear Wave Generation. Shear waves have an inherent polarization direction depending on how they are generated. Pictured below are horizontally polarized shear waves propagating along the length of a plate. Electromagnetic-acoustic transducers (EMAT) designed to generate shear waves actually vibrate the atoms within the material being investigated.

2 Jan 2013 Ultrasonic testing is a safe testing method that is widely used in various in ultrasonic flaw detection are shear waves and longitudinal waves. 21 Feb 2013 Which type(s) of sound wave modes will propagate through solids? Definition. Longitudinal, Shear & Surface waves.

A small amount of Echo Shear Wave Couplant should be placed on the face of the transducer or the test piece and then pressed into a thin layer. Shear Wave : NDTMart.com. SONATEST QUICK CHANGE SHEAR WAVE transducers are designed for use in inspections where different frequencies are required using the same wedge, or where different angles are required using the same frequency transducer. But from what I understand the shear wave probes that we use are basically the same, angled compression probes but the wave doesnt stay a longitudinal wave into the material it mode converts into a shear wave. If theyre basically the same why does one become a 45 degree shear wave and one stay a 45 degree longitudinal wave. 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.
