Verifying the base steel and welding consumables compliance with the appropriate specs. Checking for joint cleanliness and correct fit-up. Making sure that the joint layout and weld prep work is certified with the WPS and appropriate welding criteria (ASME, AWS, API).




Occasionally, pre-welding examination may discover abnormalities that are within code restrictions but can pose a concern at a later phase in production.
