These documents consist of Welding Treatment Requirements (WPS), welder credentials, examination records, project specifications, and appropriate welding codes (https://awscw1w3lding.start.page/). Prior to welding, CWIs evaluate both base steels and filler steels, keeping in mind that they conform with the WPS and task specs.

Throughout fabrication, CWIs check a selection of items to make sure that the WPS and project specs are being appropriately followed. These products include interpass temperature levels, adequate combination, cleansing, travel rate, and weld deposit dimension. Assessment throughout welding is sometimes neglected, yet it is a crucial component of making sure weld quality.

Sometimes, it may be required to test the WPS certification by performing tests on weld discount coupons (test items). Validating the base steel and welding consumables compliance with the appropriate specs. Checking for joint sanitation and correct fit-up. Ensuring that the joint design and weld preparation is compliant with the WPS and suitable welding requirements (ASME, AWS, API).


In some cases, pre-welding evaluation might discover irregularities that are within code limitations yet can position an issue at a later phase in manufacturing. That's why it's important for the welding assessor to be knowledgeable about the entire manufacturing procedure and to be experienced with the welded tools. Evaluation throughout the welding process is important for spotting the weld defects and protecting against an inaccurate welding approach from creating enormous weld denials across the whole job.
