Sometimes, it may be needed to check the WPS credentials by conducting examinations on weld coupons (examination items). Verifying the base steel and welding consumables conformity with the relevant requirements. Inspecting for joint tidiness and correct fit-up. Making sure that the joint style and weld preparation is certified with the WPS and appropriate welding requirements (ASME, AWS, API).




Occasionally, pre-welding examination may locate abnormalities that are within code limitations however might position an issue at a later stage in manufacturing.
