Validating the base metal and welding consumables conformity with the suitable specs. Evaluating for joint sanitation and correct fit-up. Making certain that the joint style and weld preparation is compliant with the WPS and suitable welding criteria (ASME, AWS, API).




Sometimes, pre-welding examination might find abnormalities that are within code restrictions yet might pose a concern at a later stage in production.
