Examining for joint cleanliness and appropriate fit-up. Making sure that the joint style and weld preparation is certified with the WPS and suitable welding criteria (ASME, AWS, API).




In some cases, pre-welding evaluation may locate abnormalities that are within code restrictions but can present a problem at a later stage in manufacturing. That's why it's important for the welding examiner to be knowledgeable about the entire manufacturing process and to be experienced look at here with the bonded devices. Evaluation throughout the welding procedure is crucial for detecting the weld defects and preventing an inaccurate welding strategy from creating large weld rejections across the whole job.
