Visual Inspection (VT)
Visual Inspection (VT) is a non-destructive examination technique that involves direct visual examination of an object’s surface to identify surface defects, neamhrialtachtaí, or visual indications of potential issues. It is one of the most basic and widely used methods of inspection in various industries.
During visual inspection, a qualified inspector visually examines the object using their eyes, along with appropriate lighting and magnification tools if needed. The goal is to detect any visible defects, cosúil le scoilteanna, creimeadh, chaitheamh, pitting, roughness dromchla, discoloration, or any other anomalies that may affect the integrity or functionality of the object.
Visual inspection can be performed at different stages of an object’s life cycle, including during manufacturing, assembly, cothabháil, or periodic inspections. It is often used as a preliminary inspection technique to identify obvious defects or abnormalities before employing more advanced non-destructive examination methods.
