The key objectives of weld assessment and high quality control are protecting against welding problems by taking restorative activities early in the manufacturing phase, and guaranteeing the high quality of the end product. As an example, a timely assessment might avoid a whole set of poor welds resulting from poor joint cleanliness or fit-up.




Sometimes, it might be necessary to examine the WPS certification by performing tests on weld promo codes (test pieces). Validating the base metal and welding consumables compliance with the applicable specs. Examining for joint sanitation and proper fit-up. Making certain that the joint style and weld prep work is compliant with the WPS and appropriate welding requirements (ASME, AWS, API).




In some cases, pre-welding assessment may locate abnormalities that are within code limitations however might posture a problem at a later phase in production. That's why it's important for the welding examiner to be accustomed to the whole production process and to be experienced with the welded equipment. Inspection throughout the welding procedure is necessary for identifying the weld flaws and stopping an incorrect welding approach from creating large weld rejections throughout the whole job.
