The size of indications is one of the most crucial pieces of information for quality assurance decisions and engineering analysis. We tend to put a lot of confidence into the sizing methods we use in ultrasonic testing but each of those methods has its limitations. This leaves one big question - do we have an overlap between the various methods or is there a gap? This video compares the methods and their limitations.

If you like my videos, the best way to support is to watch the videos all the way to the end, leave dozens of comments, give a thumbs up, and subscribe to the Channel. Or get in contact with me so that we can discuss your needs for training, consulting, and solutions.
