Time-of-flight diffraction (ToFD) ultrasonics is a non-destructive testing (NDT) technique primarily used for examining welds and other structural components for flaws and defects. It utilizes ultrasound waves to detect and characterize defects within materials by measuring the time it takes for the ultrasonic waves to travel through the material and reflect back from interfaces or discontinuities.

Water weights generally refer to weights that are filled with water to provide resistance for exercise or physical therapy. These weights can be adjusted easily by changing the amount of water they contain, allowing users to customize their workout intensity. They are often used in activities like swimming, aqua aerobics, or rehabilitation exercises. Additionally, "water weight" can also refer to the temporary weight gain that occurs due to the retention of fluid in the body.
