VISUAL TESTING & INSPECTION SERVICES (VT)

Visual Testing (VT) is a non-destructive testing (NDT) technique that involves examining the surface of a material or component to detect any visible defects or abnormalities. It is a widely used method for quality control and safety assessment in various industries such as aerospace, automotive, construction, power generation, and manufacturing.

During visual inspection, the inspector examines the surface of the material or component using the naked eye or with the help of magnifying lenses, cameras, or other visual aids. The inspector looks for surface cracks, corrosion, scratches, dents, and other surface irregularities that can affect the performance or safety of the component.

Visual inspection is often the first step in the NDT process and is usually followed by more advanced techniques such as radiography, ultrasonic testing, or eddy current testing, depending on the nature and severity of the defects detected. It is a relatively simple and cost-effective technique that can be performed quickly, making it a valuable tool for many industries.
