History of Non-Destructive Testing(NDT)
NDT began as a recognized technology, human beings have performed nondestructive tests from their beginning. Centuries before the expression NDT was first used, people “looked” at objects to determine size, shape, and even the presence of visual surface imperfections, and “listened” to metal being shaped by a blacksmith or the tone of a bell after it was cast.
