Radiography or Ultrasonic Testing? Which One Is Better? - NDT
WEBSep 13, 2019 · To give you a better overview (and hence some of the inherent advantages) of radiography and ultrasonic testing, we’ll discuss the basic mechanism of both and how they can be applied in inspection of welds. Let’s start with radiography.
NDT Levels: Easy as 1, 2, 3, Certification Explained
WEBJun 24, 2022 · RT or radiography involves using radioactive isotopes like gamma or X-rays. It examines materials and equipment like a doctor examines the human body. This certification requires you to direct radiation and read projections on a film or digital detection device. UT or ultrasonic testing uses high-frequency sound waves.
What’s the difference between UT and radiography in NDT? - NDT …
WEBUltrasonic testing (UT) and Radiographic testing (RT) are both important methods of non-destructive testing. Although they’re both used to detect flaws in components, they have different strengths and weaknesses. Let’s look at the main difference between UT and radiography first, before delving deeper.
