Validating the base steel and welding consumables compliance with the appropriate specs. Inspecting for joint tidiness and appropriate fit-up. Guaranteeing that the joint layout and weld preparation is certified with the WPS and relevant welding criteria (ASME, AWS, API).




Often, pre-welding evaluation may locate irregularities that are within code limitations yet might pose a problem at a later stage in manufacturing.
