These papers include Welding Treatment Specs (WPS), welder credentials, test records, project specifications, and appropriate welding codes (https://peatix.com/user/22320057/view). Prior to welding, CWIs examine both base steels and filler steels, noting that they conform with the WPS and job specs.


Throughout manufacture, CWIs examine a range of products to ensure that the WPS and task specifications are being appropriately adhered to. These products include interpass temperatures, adequate fusion, cleansing, travel speed, and weld down payment dimension. Assessment throughout welding is sometimes forgotten, yet it is a critical component of making certain weld top quality.

Verifying the base metal and welding consumables conformity with the relevant specifications. Making certain that the joint layout and weld preparation is compliant with the WPS and appropriate welding criteria (ASME, AWS, API).




Often, pre-welding assessment might find abnormalities that are within code restrictions yet can present an issue at a later phase in production. That's why it's essential for the welding assessor to be acquainted with the whole manufacturing process and to be experienced with the bonded equipment.
