Visual Inspection should be performed prior to each application of another inspection method to determine, partially, if the inspection should continue.  For instance, if, following a visual inspection, a crack on the surface is found, there isn’t much point in applying ultrasonic shear wave.

Many National and International visual inspection certifications exist which rely on the eyes of the inspector to find flaws in many different types of equipment such as:

API 510 for Pressure Vessels
API 570 for Pressure Piping
API 653 for Above Ground Storage Tanks
AWS CWI for Welding Inspection


Obtaining a good background in Visual Inspection is generally regarded as necessary to make inspection personnel the best that they can be, regardless of the method to be employed.

Visual Inspection is the use of the eye to conduct an inspection.  Some say that all inspection is, at the heart, a visual inspection.  Methods such as Magnetic Particle or Liquid Dye Penetrant are methods that directly use the eye to determine the presence of a discontinuity by increasing the contrast between the inspection surface and the defect.
