Often, it might be necessary 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 correct fit-up. Making certain that the joint design and weld preparation is compliant with the WPS and applicable welding standards (ASME, AWS, API).




Sometimes, pre-welding examination might find abnormalities that are within code constraints however could posture a problem at a later stage in manufacturing.
