2. Weld quality assurance - Wikipedia

   en.wikipedia.org/wiki/Weld_quality_assurance

   Weld mapping is the process of assigning information to a weld repair or joint to enable easy identification of weld processes, production (welders, their qualifications, date welded), quality (visual inspection, NDT, standards and specifications) and traceability (tracking weld joints and welded castings, the origin of weld materials).

3. 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.

4. 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.

5. Engineering Critical Assessment - Wikipedia

   en.wikipedia.org/wiki/Engineering_Critical...

   Engineering Critical Assessment (ECA) is a procedure by which the safety of a welded structure with defects or flaws can be determined. ECAs utilize the material properties and expected stress history to determine a flaw acceptance criteria which will ensure that welds will not fail during the construction or service life of the welded structure. [1]
