The main objectives of weld inspection and quality assurance are preventing welding defects by taking restorative actions early in the production phase, and ensuring the quality of completion item. A prompt examination might prevent an entire set of poor welds resulting from poor joint cleanliness or fit-up.




Often, it may be essential to check the WPS qualification by conducting examinations on weld vouchers (test pieces). Validating the base metal and welding consumables compliance with the applicable specs. Evaluating for joint cleanliness and appropriate fit-up. Making sure that the joint design and weld prep work is compliant with the WPS and appropriate welding criteria (ASME, AWS, API).




In some cases, pre-welding inspection may locate abnormalities that are within code constraints however could pose a concern at a later phase in production. That's why it's important for the welding inspector to be accustomed to the whole manufacturing procedure and to be experienced with the bonded devices. Assessment during the welding process is vital for detecting the weld issues and stopping a wrong welding strategy from triggering huge weld beings rejected throughout the whole task.
