The key goals of weld assessment and high quality control are protecting against welding flaws by taking restorative actions at an early stage in the manufacturing phase, and ensuring the quality of completion item. As an example, a prompt examination can avoid an entire set of negative welds arising from poor joint tidiness or fit-up.




In some cases, it may be necessary to test the WPS certification by carrying out examinations on weld vouchers (test pieces). Validating the base steel and welding consumables compliance with the appropriate requirements. Inspecting for joint tidiness and correct fit-up. Ensuring that the joint style and weld prep work is compliant with the WPS and appropriate welding criteria (ASME, AWS, API).




Often, pre-welding evaluation may find abnormalities that are within code constraints however might pose an issue at a later phase in manufacturing. That's why it's important for the welding inspector to be accustomed to the whole production process and to be experienced with the bonded devices. Evaluation during the welding procedure is essential for detecting the weld flaws and avoiding an incorrect welding approach from creating large weld beings rejected across the whole job.
