These documents consist of Welding Procedure Specifications (WPS), welder certifications, test records, job specifications, and applicable welding codes. A good CWI knows and comprehends the specs and code. After that, she or he sees to it that the WPS and welder credentials adapt those needs. Before welding, CWIs evaluate both base steels and filler steels, keeping in mind that they abide by the WPS and task requirements.


Throughout manufacture, CWIs examine a range of things to guarantee that the WPS and task specifications are being properly adhered to. These items consist of interpass temperature levels, sufficient blend, cleansing, travel speed, and weld down payment dimension. Evaluation throughout welding is sometimes neglected, yet it is a crucial component of ensuring weld high quality.
