NDE Inspection - Visual Testing (VT)

The most basic and effective NDE inspection method is visual examination. Visually inspecting a part for surface imperfections is typically the first step in any examination process.  It is the most primitive and cost effective inspection method when utilized properly.

The American Welding Society (AWS) requirements of visual testing typically pertain to three areas:

  • The inspector’s vision
  • The amount of light falling on the specimen, which is measured using a light meter
  • Whether the area being inspected is obstructed from view.

CWI’s and VT Level II’s perform visual inspections based on the acceptance standards of the applicable construction codes that they are working too.
