These files include Welding Procedure Specifications (WPS), welder qualifications, examination documents, job requirements, and suitable welding codes. A great CWI understands and recognizes the requirements and code. After that, she or he makes certain that the WPS and welder credentials adapt those requirements. Before welding, CWIs evaluate both base metals and filler metals, keeping in mind that they conform with the WPS and task requirements.


During manufacture, CWIs check a selection of products to make certain that the WPS and project specifications are being properly complied with. These items consist of interpass temperatures, adequate fusion, cleansing, travel speed, and weld deposit dimension. Inspection throughout welding is often ignored, however it is a critical component of making certain weld quality.
