VT — Visual Inspection

A non-destructive testing method that uses direct or indirect visual examination to assess the condition of materials, components and equipment.

Definition

Visual Inspection (VT) is a non-destructive testing (NDT) method that uses direct observation or optical aids to examine the condition of materials, welds, equipment and structures for visible indications of damage, deterioration or non-conformance. Visual Inspection is commonly the first inspection technique applied before more specialized non-destructive testing methods are performed.

Why It Matters

Visual Inspection provides non-destructive assessment of visible conditions, defects and deterioration affecting engineering assets.

In Practice

Visual Inspection may be performed using the unaided eye or optical devices such as mirrors, borescopes, cameras or drones, depending on accessibility and inspection requirements.

Common Misuse

Visual Inspection evaluates visible surface conditions without damaging the asset, whereas other non-destructive testing methods such as Ultrasonic Testing and Radiographic Testing are used to detect subsurface or internal discontinuities.
