Sometimes, it may be essential to check the WPS certification by conducting examinations on weld coupons (examination pieces). Verifying the base steel and welding consumables conformity with the relevant requirements. Inspecting for joint cleanliness and proper fit-up. Making certain that the joint layout and weld prep work is compliant with the WPS and applicable welding requirements (ASME, AWS, API).
