Often, it might be essential to check the WPS credentials by conducting examinations on weld discount coupons (test items). Verifying the base metal and welding consumables compliance with the appropriate requirements. Checking for joint sanitation and proper fit-up. Making certain that the joint layout and weld prep work is certified with the WPS and applicable welding requirements (ASME, AWS, API).




Often, pre-welding assessment may locate abnormalities that are within code limitations yet might posture a problem at a later stage in manufacturing.
