In some cases, it may be essential to examine the WPS certification by conducting examinations on weld vouchers (test items). Verifying the base steel and welding consumables compliance with the appropriate specifications. Checking for joint sanitation and appropriate fit-up. Making certain that the joint design and weld preparation is certified with the WPS and appropriate welding criteria (ASME, AWS, API).




In some cases, pre-welding evaluation may find abnormalities that are within code constraints yet might present a problem at a later phase in production. That's why it's crucial for the welding assessor to be accustomed to the entire production process and to be experienced with the welded equipment. Assessment during the welding procedure is vital for detecting the weld issues and stopping a wrong welding approach from causing large weld denials throughout the whole task.
