NDT Teaching Tips

 

Physics educators always seem to have so much fun with all their little experiments that demonstrate the various interactions between time, space, energy and matter. Since NDT is basically applied physics, why shouldn't NDT instructors have some fun too. The information on this page was developed to provide instructors with some experiments and demonstrations that can be done to help students grasp the science of NDT. An understanding of the science that drives NDT measurement is essential in developing technicians the strong problem solving skills that industry is demanding.
