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. Plastic weld non-destructive examination - Wikipedia

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

   In-process inspections can show problems with the weld such as discoloration, indicating thermal degradation, bubbles, scratches, and weld bead problems. Visual inspection of the completed weld can detect joint fit-up and tool problems such as mismatch, angular misalignment, notches, and insufficient weld size as well as surface breaking weld ...

4. Testing of advanced thermoplastic composite welds - Wikipedia

   en.wikipedia.org/wiki/Testing_of_Advanced...

   Visual Inspection (VT) is typically the first option for any attempt at NDT, being the least expensive, as it requires the least specialized training and usually few if any special tools. Defects on the surfaces of thermoplastic composite welds can be detected visually if they are of sufficient size.

5. Nondestructive testing - Wikipedia

   en.wikipedia.org/wiki/Nondestructive_testing

   In the case of high stress or safety critical welds, weld monitoring will be employed to confirm the specified welding parameters (arc current, arc voltage, travel speed, heat input etc.) are being adhered to those stated in the welding procedure. This verifies the weld as correct to procedure prior to nondestructive evaluation and metallurgy ...

6. 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.

7. 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.
