In some cases, it may be required to examine the WPS qualification by carrying out tests on weld coupons (examination items). Verifying the base metal and welding consumables conformity with the relevant requirements. Inspecting for joint cleanliness and correct fit-up. Guaranteeing that the joint style and weld preparation is certified with the WPS and applicable welding requirements (ASME, AWS, API).




Sometimes, pre-welding evaluation might find irregularities that are within code constraints yet might posture a concern at a later stage in manufacturing. That's why it's essential for the welding assessor to be knowledgeable about the entire production process and to be experienced with the bonded tools. Evaluation throughout the welding process is crucial for spotting the weld issues and avoiding an inaccurate welding approach from creating enormous weld beings rejected throughout the whole project.
