In some cases, it might be required to check the WPS qualification by conducting tests on weld promo codes (examination items). Confirming the base metal and welding consumables conformity with the appropriate specs. Evaluating for joint sanitation and correct fit-up. Making sure that the joint design and weld preparation is compliant with the WPS and appropriate welding requirements (ASME, AWS, API).




Sometimes, pre-welding assessment might locate abnormalities that are within code constraints yet can posture a problem at a later phase in manufacturing.
