Visual Inspection Testing

Visual Inspection Testing

Visual Inspection is one of the most widely used Non-Destructive Testing methods for the detection of discontinuities before they cause major problems, e.g. poor welding, surface defects, corrosion pits, general condition, degradation, blockages and foreign materials.

Visual Inspection means the inspection of equipment and structures using a combination of human senses such as vision, hearing, touch and smell. Visual Inspection is sometimes carried out in conjunction with devices such as a low power magnifying glass, boroscopes, fiberscopes, digital video bore scopes, camera systems and robotic crawler systems.

When attempting to determine the soundness of any part or specimen for its intended application, visual inspection is normally the first step in the examination process. Generally, almost any specimen can be visually examined to determine the accuracy of its fabrication. For example, visual inspection can be used to determine whether the part was fabricated to the correct size, whether the part is complete, or whether all of the parts have been appropriately incorporated into the device. While direct visual inspection is the most common nondestructive testing technique, many other NDT methods require visual intervention to interpret images obtained while carrying out the examination. For instance, penetration inspection using visible red or fluorescent dye relies on the inspector's ability to visually identify surface indications. Magnetic particle inspection falls into the same category of visible and fluorescent inspection techniques, and radiography relies on the interpreter's visual judgment of the radiographic image, which is either on film or on a video monitor.
