Visual testing is the most commonly used nondestructive testing method in the industry. Most test methods require that the inspector looks at the surface of the part being inspected which means that visual inspection is the first step for these other test methods. As the name implies, VT involves the visual observation of the surface of a test object to evaluate the presence of surface discontinuities. VT inspections may be by direct viewing, using line-of-sight vision, or enhanced viewing methods. Corrosion, misalignment of parts, physical damage and cracks are just some of the discontinuities that may be detected by visual examinations. Corrosion, misalignment, physical damage, and cracks are just some of the discontinuities that may be identified by visual inspection.
