Sometimes, it might be needed to check the WPS certification by conducting examinations on weld discount coupons (test pieces). Validating the base metal and welding consumables conformity with the relevant requirements. Inspecting for joint cleanliness and proper fit-up. Making certain that the joint style and weld prep work is certified with the WPS and relevant welding criteria (ASME, AWS, API).




Sometimes, pre-welding assessment may discover abnormalities that are within code restrictions however could pose a problem at a later phase in manufacturing.
