2. Weld quality assurance - Wikipedia

   en.wikipedia.org/wiki/Weld_quality_assurance

   Inspection may be manual, conducted by an inspector using imaging equipment, or automated using machine vision. [citation needed] Since the similarity of materials between weld and workpiece, and between good and defective areas, provides little inherent contrast, the latter usually requires methods other than simple imaging.

3. Plastic weld non-destructive examination - Wikipedia

   en.wikipedia.org/wiki/Plastic_weld_non...

   During laser welding, air bubbles can form and cause a degradation in the mechanical properties of the joint. Current inspection techniques are limited to finding air bubbles on the surface of the weld (optical and scanning electron microscopy). Destructive testing is usually required to find volumetric flaws.

4. Welder certification - Wikipedia

   en.wikipedia.org/wiki/Welder_certification

   In addition to welders and welding machine operators, there are also schemes to independently certify welding inspectors and related specialities. The duties of the welding inspector are described in ISO 14731; [12] however the requirement for inspector certification are not standardized, so there are differences in requirement between the various schemes.

   Risk-based inspection – an Optimal maintenance business process used to examine equipment such as pressure vessels, heat exchangers and piping in industrial plants; Robotic non-destructive testing – Method of inspection using remotely operated tools

6. Dye penetrant inspection - Wikipedia

   en.wikipedia.org/wiki/Dye_penetrant_inspection

   5. Inspection: The inspector will use visible light with adequate intensity (100 foot-candles or 1100 lux is typical) for visible dye penetrant. Ultraviolet (UV-A) radiation of adequate intensity (1,000 micro-watts per centimetre squared is common), along with low ambient light levels (less than 2 foot-candles) for fluorescent penetrant ...
