In some cases, it might be necessary to check the WPS qualification by carrying out examinations on weld coupons (test items). Verifying the base metal and welding consumables conformity with the relevant specifications. Checking for joint sanitation and proper fit-up. Making sure that the joint layout and weld prep work is compliant with the WPS and appropriate welding requirements (ASME, AWS, API).




Occasionally, pre-welding inspection might locate abnormalities that are within code restrictions yet can posture a concern at a later stage in manufacturing.
