The main goals of weld assessment and high quality control are stopping welding problems by taking corrective activities beforehand in the manufacturing stage, and guaranteeing the top quality of completion product. As an example, a prompt evaluation might avoid a whole set of poor welds resulting from poor joint sanitation or fit-up.




Often, it might be needed to test the WPS credentials by conducting tests on weld promo codes (examination pieces). Confirming the base metal and welding consumables conformity with the relevant specifications. Checking for joint tidiness and correct fit-up. Ensuring that the joint style and weld preparation is compliant with the WPS and suitable welding criteria (ASME, AWS, API).




Occasionally, pre-welding examination might find abnormalities that are within code restrictions however can pose a problem at a later stage in manufacturing. That's why it's important for the sites welding inspector to be aware of the entire manufacturing process and to be experienced with the welded devices. Evaluation throughout the welding procedure is important for spotting the weld issues and stopping an incorrect welding strategy from triggering huge weld rejections throughout the entire task.
