Sizing of Small Defects with Ultrasonic Testing: Don't use Flat Bottom Holes!!!

Accurately sizing tiny defects in Ultrasonic Testing can be a major headache—and traditional methods might be leading you astray. When dealing with indications smaller than a single wavelength, standard practices like using Flat Bottom Holes (FBHs) can result in critical undersizing and flawed evaluations. In this deep-dive video, we break down the physics behind acoustic scattering, explore advanced EFIT simulations, and reveal why FBHs are a poor model for small defects. Level up your NDT inspection accuracy and discover the right approach to sizing sub-wavelength indications with confidence. Watch now to refine your UT techniques and avoid costly sizing mistakes!
