Close Visual Inspection (CVI)

As the name suggests, this is a detailed and close up visual examination of welds / structures / vessels / pipework. The qualifications applicable to CVI can be both PCN or CSWIP. We have experienced inspectors qualified in both.

CVI of Welds

Typically CVI would be used to identify areas requiring more in-depth inspection. Examples of its application could be identification of pipework likely to require further wall thickness checks (see Ultrasonic Testing), newly fabricated assemblies require CVI pre further NDT (MPI/UT), in-situ structural assemblies require a CVI to detect fatigue induced cracking prior to further NDT (ECI/MPI), etc.
