What is visual inspection of welds?

Visual inspection is conducted to identify surface flaws or conditions, that are visible to the naked eye. A visual inspector will examine the weld or asset visually and determine if any discontinuities or issues are present. This insection method also allows the inspector to uncover issues related to geometry of a weld or the condition of an asset. This non-destructive testing method is commonly used as a first step in welding or asset inspections, as it is a quick way to determine if any initial concerns are present. However, this inspection method has several limitations, including the fact that it can only be used to identify flaws that are visible. As well, visual inspections on welds may be conducted throughout the process to ensure a successful outcome.
