Often, it might be essential to evaluate the WPS certification by performing examinations on weld coupons (test pieces). Confirming the base steel and welding consumables conformity with the applicable specifications. Examining for joint tidiness and appropriate fit-up. Ensuring that the joint design and weld preparation is compliant with the WPS and appropriate welding requirements (ASME, AWS, API).




Often, pre-welding assessment might find irregularities that are within code constraints however could present a problem at a later phase in production. That's why it's vital for the welding assessor to be accustomed to the entire production procedure and to be experienced with the welded tools. Evaluation throughout the welding procedure is important for detecting the weld problems and avoiding a wrong welding technique from causing massive weld denials across the whole project.
