In some cases, it might be essential to evaluate the WPS certification by performing tests on weld discount coupons (examination items). Validating the base metal and welding consumables compliance with the appropriate specs. Evaluating for joint sanitation and proper fit-up. Guaranteeing that the joint style and weld prep work is certified with the WPS and applicable welding standards (ASME, AWS, API).




Occasionally, pre-welding assessment may find abnormalities that are within code restrictions however could posture a problem at a later stage in manufacturing. That's why it's essential for the welding examiner to be familiar with the whole production procedure and to be experienced with the bonded equipment.
