Prior to welding, CWIs inspect both base steels and filler steels, keeping in mind that they comply with the WPS and task specifications.


Throughout fabrication, CWIs examine a variety of items to ensure that the WPS and project specs are being appropriately adhered to. These items include interpass temperatures, adequate combination, cleaning, traveling rate, and weld deposit size. Assessment throughout welding is in some cases ignored, but it is a critical part of making certain weld quality.
