Often, it may be needed to test the WPS credentials by performing examinations on weld promo codes (test items). Confirming the base metal and welding consumables compliance with the relevant requirements. Checking for joint tidiness and appropriate fit-up. Guaranteeing that the joint design and weld prep work is certified with the WPS and appropriate welding standards (ASME, AWS, API).




Sometimes, pre-welding examination may locate abnormalities that are within code restrictions but can present a concern at a later stage in production. That's why it's vital for the welding examiner to be accustomed to the whole manufacturing procedure and to be experienced with the bonded equipment.
