Visual testing (VT)

Visual testing is a mainstay of surface inspection performed before all other non-destructive tests. Visual testing only allows the detection of imperfections formed on the surface of welded joints. Observations are made from the side of the face and the root (if access is provided) using the naked eye or with mirrors, loupes, etc.
