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).
Radiography uses an X-ray tube or radioactive source to give an image of the weld. Its use is similar to metal welds and provides a volumetric inspection which can show defects in the weld not visible from the surface. For plastics, a lower radiation intensity is typically required than that for metal welds, due to the lower material density. [1]
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 ...
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.

PCN Level 3 Weld Inspection with radiographic interpretation; The Welding Institute (TWI) in the United Kingdom offers the following certification scheme: [16] CSWIP 3.0 (Level 1): Visual Welding Inspector; CSWIP 3.1 (Level 2): Welding Inspector; CSWIP 3.2 (Level 3): Senior Welding Inspector; with or without radiographic interpretation (3.2.1 ...
Pulse IRNDT analysis can be successfully used for weld inspection in many cases. The images show an example of plastic parts inspection with a defective weld and with a correct weld. The gaps in the defective weld and the correct uninterrupted weld line are both well visible in the results of the IRNDT flash-pulse analysis.

Dye penetrant inspection (DP), also called liquid penetrate inspection (LPI) or penetrant testing (PT), is a widely applied and low-cost inspection method used to check surface-breaking defects in all non-porous materials (metals, plastics, or ceramics).
