The key objectives of weld assessment and quality assurance are stopping welding problems by taking corrective activities at an early stage in the manufacturing stage, and ensuring the top quality of the end item. For instance, a timely examination might prevent an entire batch of negative welds resulting from inadequate joint cleanliness or fit-up.



Occasionally, it might be necessary to evaluate the WPS credentials by carrying out examinations on weld coupons (test items). Validating the base metal and welding consumables compliance with the relevant specifications. Evaluating for joint sanitation and appropriate fit-up. Making certain that the joint design and weld preparation is certified with the WPS and appropriate welding requirements (ASME, AWS, API).


In some cases, pre-welding evaluation might locate irregularities that are within code limitations but can present an issue at a later phase in manufacturing. That's why it's important for the welding assessor to be acquainted with the entire production procedure and to be experienced with the welded equipment. Examination during the welding process is essential for finding the weld defects and preventing an incorrect welding technique from creating massive weld beings rejected across the entire job.
