Exam Specifications - Ultrasonic Testing: Shear Wave Pressure Equipment Weld Examination (UTSW) A hands-on practical examination will be used to assess the candidate's ability to perform ultrasonic testing (UT) on a minimum number of specimens and product forms per the shear wave pressure equipment weld ISQ exam. Shear Wave sometimes referred to as Angled Beam Ultrasonic testing is a portable testing method that offers an effective test for weld inspection in pipes, pressure vessels, plates or in areas that other test methods are not feasible or particle. 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. One example, when dealing with shear wave, is porosity that will fail on RT can pass with UT. Due to the ability of RT to see round indications and the difficulty, regardless of the tech's ability, to get a reflection to return with shear wave.
