Verifying the base metal and welding consumables compliance with the suitable requirements. Evaluating for joint sanitation and proper fit-up. Guaranteeing that the joint design and weld preparation is compliant with the WPS and appropriate welding requirements (ASME, AWS, API).


Sometimes, pre-welding examination might discover irregularities that are within code limitations but could pose a concern at a later phase in manufacturing.
