Prior to welding, CWIs check both base steels and filler metals, keeping in mind that they comply with the WPS and job requirements.


During construction, CWIs examine a range of things to ensure that the WPS and job requirements are being correctly complied with. These items include interpass temperature levels, adequate combination, cleaning, travel speed, and weld down payment dimension. Evaluation throughout welding is occasionally overlooked, however it is an essential part of making certain weld quality.

After a weld is finished, a CWI will check it carefully, inspecting and determining any type of interruptions such as porosity, undercut, splits, insufficient fusion, or insufficient profile. The dimension of the weld is likewise determined for uniformity to the project specs. If any one of the discontinuities do not abide by task needs, they are taken into consideration flaws and should be repaired.
