Prior to welding, CWIs evaluate both base steels and filler steels, keeping in mind that they adhere to the WPS and project specs.


During fabrication, CWIs check a selection of products to make sure that the WPS and task specs are being correctly adhered to. These products include interpass temperatures, sufficient blend, cleaning, travel rate, and weld deposit dimension. Examination during welding is sometimes overlooked, but it is a critical component of ensuring weld quality.

Often, it may be needed to evaluate the WPS certification by conducting tests on weld vouchers (test items). Confirming the base metal and welding consumables conformity with the applicable requirements. Inspecting for joint cleanliness and appropriate fit-up. Making certain that the joint style and weld prep work is compliant with the WPS and suitable welding requirements (ASME, AWS, API).




In some cases, pre-welding assessment might discover abnormalities that are within code constraints however can posture a problem at a later phase in manufacturing. That's why it's essential for the welding examiner to be aware of the whole manufacturing procedure and to be experienced with the bonded devices. Evaluation during the welding procedure is important for spotting the weld issues and stopping an incorrect welding approach from creating enormous weld rejections throughout the entire task.
