In some cases, it might be essential to evaluate the WPS certification by conducting tests on weld vouchers (examination items). Verifying the base metal and welding consumables conformity with the applicable specs. Evaluating for joint cleanliness and correct fit-up. Ensuring that the joint style and weld prep work is compliant with the WPS and suitable welding standards (ASME, AWS, API).




Often, pre-welding evaluation may locate abnormalities that are within code limitations however might position an issue at a later stage in manufacturing. That's why it's important for the welding assessor to be knowledgeable about the whole manufacturing process and to be experienced with the bonded equipment. Assessment throughout the welding procedure is essential for spotting the weld issues and protecting against an inaccurate welding approach from creating substantial weld beings rejected across the whole job.
