Prior to welding, CWIs inspect both base metals and filler steels, noting that they abide by the WPS and job specs.


Throughout fabrication, CWIs examine a variety of items to make certain that the WPS and job specs are being correctly complied with. These items include interpass temperatures, ample fusion, cleaning, traveling speed, and weld deposit size. Evaluation during welding is in some cases forgotten, but it is an important component of ensuring weld high quality.
