The key objectives of weld assessment and high quality control are stopping welding defects by taking rehabilitative actions early on in the manufacturing stage, and making sure the quality of completion product. As an example, a timely evaluation can stop an entire batch of negative welds resulting from bad joint cleanliness or fit-up.




Occasionally, it may be required to examine the WPS certification by performing tests on weld promo codes (examination pieces). Confirming the base metal and welding consumables compliance with the relevant specifications. Examining for joint tidiness and correct fit-up. Ensuring that the joint style and weld preparation is compliant with the WPS and applicable welding requirements (ASME, AWS, API).




In some cases, pre-welding inspection might locate abnormalities that are within code restrictions but can present an issue at a later phase in production.
