The main goals of weld assessment and quality control are stopping welding problems by taking restorative actions early on in the production phase, and guaranteeing the quality of completion product. As an example, a prompt evaluation could protect against an entire batch of bad welds arising from bad joint tidiness or fit-up.




Often, it may be required to test the WPS credentials by conducting tests on weld discount coupons (test items). Confirming the base steel and welding consumables compliance with the suitable requirements. Checking for joint sanitation and proper fit-up. Guaranteeing that the joint design and weld prep work is compliant with the WPS and appropriate welding standards (ASME, AWS, API).




Often, pre-welding examination may discover abnormalities that are within code constraints however could posture a problem at a later phase in production. That's why it's important for the welding assessor to be aware of the whole production process and to be experienced with the bonded devices. Examination during the welding process is vital for spotting the weld defects and protecting against an incorrect welding technique from creating huge weld beings rejected across the whole project.
