Visual examination is one of the most often used NDT techniques. This NDT technique, also known as visual testing, is thought to be the most fundamental and traditional of its kind. After all, the naked eye or the sense of sight, as well as one’s hearing, smell, and touch, were what were initially necessary to visually assess assets. Visual examination was widely utilised to assess objects, places, and structures back then because there weren’t any special inspection instruments, equipment, or gadgets available.

Visual inspection is the observation of any component, joint, or other piping element that is subject to such observation prior to, during, or after manufacturing, fabrication, assembly, erection, inspection, or testing.
