The original British and European standard governing the visual examination of fusion-welded joints.
Inspectors must be trained, qualified, and certified in accordance with recognized standards like BS EN ISO 9712 (or CSWIP/PCN schemes). They must possess a solid understanding of welding processes, welding defects, and acceptance criteria.

The inspector’s eye must be within 600 mm of the weld surface.
In the world of manufacturing and construction, the integrity of a weld can mean the difference between a safe, long-lasting structure and a catastrophic failure. Visual inspection is the first line of defense in non-destructive testing (NDT). It is the only NDT method that provides a direct, immediate, and holistic assessment of weld quality. The standard that has long governed this practice in the UK and across Europe is , titled "Non-destructive examination of fusion welds — Visual examination". The original British and European standard governing the
