Visual Inspection

Non-Destructive Inspection (NDI), also known as Non-Destructive Testing (NDT), is a method which involves both direct and indirect visual techniques. Direct Testing is where the material is inspected directly by the human eye with no additional visual aids. Indirect Testingmay involve the use of magnifying glasses, mirrors, boroscopes (mini cameras), CCTV etc.

Visual Inspection is a Conventional Testing Method that is crucial although often dismissed, however this should be the basis for inspectors starting out in the NDT industry.

For example, a visual examination of an operational plant can often reveal obvious problem areas such as leaks, excess vibration, corrosion or misalignment. This Testing is a very cost-effective exercise and can be used to identify areas that require special examinations.
