The main objectives of weld examination and quality assurance are protecting against welding flaws by taking corrective activities at an early stage in the manufacturing phase, and ensuring the quality of completion product. A prompt assessment might avoid an entire batch of poor welds resulting from poor joint tidiness or fit-up.




Confirming the base steel and welding consumables conformity with the relevant specifications. Guaranteeing that the joint style and weld prep work is certified with the WPS and applicable welding standards (ASME, AWS, API).




Occasionally, pre-welding evaluation may find irregularities that are within code restrictions but can position an issue at a later phase in production. That's why it's vital for the welding assessor to be acquainted with the entire manufacturing process and to be experienced with the bonded devices. Inspection throughout the welding process is vital for spotting the weld issues and stopping an incorrect welding strategy from causing substantial weld denials across the whole project.
