A pulse is sent to the piezoelectric element, the element expands and produces a longitudinal wave into the wedge 2021-03-01 Certified Level II UT Shear Wave. Desired Competencies Strong work ethic Dependable Exceptional safety and quality awareness Mechanical aptitude Adaptable to changing schedules Exceptional attention to detail Team work Ability to follow directions and procedures. Physical Demands and … Industry-qualified UT shear wave examiner A person who possesses an ultrasonic shear wave qualification from API (e.g. API-QUTE) or an equivalent qualification approved by the owner/user.

following shear wave angles are recommended: 70” for plate thicknesses 1/4” to 1/2” 60° or 70° for platiethicknesses 1/2” to 1-1/2’” 45° or 60° for plate thicknesses l-l\2° to 2-112”. The transducer angle should be checked periodically with the International Xnstitute of Welding Test Block, Fig. A-2. Material: Ultrasonic Velocity: Longitudinal: Transverse (Shear) Impedance in / us: mm / us: in / us: mm / us: Z: Metals: Aluminum 1100-0: 0.248: 6.229: 0.121: 3.073 Ultrasonic testing instrument shall be calibrated for the examination and shall be capable of meeting the requirements of screen height linearity and amplitude control linearity in paragraph 5.3 & 5.4 of this procedure.(Trade name of ultrasonic testing instrument is krautkramer USN-52) Ultrasonic testing instrument shall be equipped with Shear waves are different from longitudinal waves in terms of several characteristics including wavelength, oscillation mode, velocity, and attenuation. Generally, using shear waves allows you to detect smaller discontinuities due to their shorter wavelength (as compared to the longitudinal wave). Shear wave UT is very useful for detecting cracks and provides essentially the only method for determining the size (depth) of cracks with sufficient accuracy for making a fitness-for-service analysis to evaluate the integrity and reliability of a vessel.

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.
