In some cases, it might be essential to evaluate the WPS certification by conducting examinations on weld discount coupons (examination items). Confirming the base steel and welding consumables conformity with the relevant specs. Checking for joint sanitation and proper fit-up. Guaranteeing that the joint layout and weld prep work is certified with the WPS and suitable welding standards (ASME, AWS, API).




Occasionally, pre-welding examination might discover abnormalities that are within code restrictions but can present a problem at a later stage in manufacturing.
