Validating the base metal and welding consumables compliance with the applicable requirements. Evaluating for joint sanitation and proper fit-up. Making sure that the joint style and weld prep work is certified with the WPS and suitable welding criteria (ASME, AWS, API).




Often, pre-welding evaluation may locate irregularities that are within code limitations however can present an issue at a later phase in production.
