The key goals of weld assessment and quality control are stopping welding problems by taking rehabilitative actions early on in the manufacturing stage, and ensuring the high quality of the end item. For example, a prompt inspection might avoid an entire batch of poor welds resulting from bad joint cleanliness or fit-up.



Validating the base steel and welding consumables conformity with the relevant specifications. Ensuring that the joint design and weld preparation is compliant with the WPS and appropriate welding requirements (ASME, AWS, API).


Sometimes, pre-welding inspection might discover irregularities that are within code constraints yet might position a concern at a later phase in production. That's why it's vital for the welding assessor to be aware of the entire manufacturing process and to be experienced with the welded tools. Evaluation throughout the welding procedure is necessary for finding the weld defects and preventing a wrong welding strategy from triggering enormous weld rejections throughout the entire job.
