Often, it may be needed to check the WPS credentials by conducting examinations on weld coupons (test pieces). Confirming the base steel and welding consumables conformity with the appropriate specifications. Examining for joint tidiness and correct fit-up. Guaranteeing that the joint style and weld prep work is certified with the WPS and suitable welding standards (ASME, AWS, API).




Occasionally, pre-welding assessment may find irregularities that are within code limitations but can present a problem at a later stage in manufacturing.
