Description
Summary:The use of Reflectivity Curves and the Distance Gain Size (DGS) method are useful techniques for the sizing of discontinuities using Ultrasonics. The principal works on the theoretical relationship between the signal of a reflector at a specific distance and amplitude when compared to a known reflector. These assessments are typically carried out in two ways: • Use of Reflectivity Curves • DGS Software or Calculations This paper will cover the basis behind the development of these curves and the DGS system.
