This course covers the basic theory and equipment operation associated with the time of flight diffraction (TOFD) technique. Our training classes blend theoretical training and lab exercises to help maximize the learning potential. We prepare you by training with state of the art equipment and have one the largest collections of real flawed samples which also help prepare individuals for the real world.
This 40 Hour will fill the formal training requirements if seeking certification in TOFD to SNT-TC-1A or CP-189. This class follows and fulfills the Topical Outline for Qualification of Nondestructive Testing Personnel CP-105.
