tube, very thick viscosity paste (minimum of 2) UT-EU-SH-02 –+ NDT Penetrant Testing Systems Due to diffraction, wave interference and the complexity of mode conversions, the accuracy of transmitted shear wave NDT is not always better than transmitted longitudinal wave NDT. Shear wave, also known as angle-beam testing, is commonly used for flaw detection and the inspection of new construction welds, structural steel welds, and in-service welds. JANX carries out shear-wave flaw detection and pipe inspection in accordance with all applicable codes. Benefits. Mobile. Portable.

1986-01-01 · Shear wave scanning of rods and pipes There are many industrial components such as rods and pipes which have a circularly cylindrical geometry. Defects can occur both in the manufacturing and in the in-service lifetime of these component~ Apart from compression wave testing, shear waves are also used in NDT for detecting such defects. The ultrasonic shear wave method is a technique which encompasses angle beam ultrasonic testing to identify subsurface anomalies not found directly underneath the transducer itself. Shear wave ultrasonic testing uses ultrasonic energy that is reflected back to the transducer from indications within a material and or weld.
