These records include Welding Treatment Requirements (WPS), welder certifications, examination documents, task specifications, and appropriate welding codes. A great CWI recognizes and recognizes the requirements and code. Then, he or she ensures that the WPS and welder certifications adapt to those needs. Prior to welding, CWIs check both base steels and filler steels, keeping in mind that they follow the WPS and project specifications.

Throughout fabrication, CWIs examine a variety of items to make sure that the WPS and project specs are being appropriately followed. These products consist of interpass temperature levels, sufficient blend, cleaning, travel rate, and weld down payment size. Assessment during welding is sometimes ignored, but it is an important part of guaranteeing weld top quality.
