Question

Quizplus · Accepted Answer

Ultrasonic testing (UT) using a combination of velocity ratio and backscatter has been the most successful in finding cracking caused by high temperature hydrogen attack. This is because UT is able to penetrate deep into the material and can detect small cracks and defects. The velocity ratio technique compares the velocity of sound waves as they travel through the material and the backscatter technique uses reflections from the material to detect cracks.
