A great CWI understands and comprehends the specifications and code. He or she makes sure that the WPS and welder qualifications adhere to those requirements. Prior to welding, CWIs inspect both base metals and filler metals, keeping in mind that they adhere to the WPS and task specifications.


Throughout construction, CWIs examine a range of things to guarantee that the WPS and task requirements are being correctly complied with. These things consist of interpass temperatures, appropriate fusion, cleaning, traveling rate, and weld down payment size. Evaluation throughout welding is occasionally overlooked, however it is an essential part of guaranteeing weld high quality.

After a weld is completed, a CWI will evaluate it very closely, checking and determining any gaps such as porosity, undercut, splits, insufficient fusion, or inadequate profile. The size of the weld is also measured for uniformity to the project specifications. If any of the suspensions do not abide with project requirements, they are considered problems and must be fixed.


Examination takers should score 72% or even more on all three parts to gain the CWI qualification. Likewise, AWS requires an eye test and a mix of education and job experience.

The key goals of weld inspection and top quality control are protecting against welding problems by taking corrective activities at an early stage in the manufacturing stage, and making certain the high quality of completion product. A timely assessment can prevent a whole set of negative welds resulting from poor joint sanitation or fit-up.




Verifying the base metal and welding consumables compliance with the applicable specifications. Ensuring that the joint design and weld prep work is certified with the WPS and relevant welding criteria (ASME, AWS, API).




In some cases, pre-welding inspection might find abnormalities that are within code restrictions but can position an issue at a later phase in production. That's why it's crucial for the welding inspector to be knowledgeable about the entire manufacturing process and to be experienced with the bonded devices. Inspection throughout the welding process is essential for detecting the weld problems and preventing an inaccurate welding approach from triggering huge weld rejections across the whole job.

3 Easy Facts About Aws Cwi Described

One more instance would certainly be not examining for extreme distortion, which would certainly cause weld rejection and expensive rework if done on pricey tools like heat exchangers, distillation columns, and boilers. A few of the typical quality control checks during welding are: Verification of pre-heat and interpass temperatures and making certain that they are within limits specified in the WPS.


Confirm the protecting gas and flux are as advised in the WPS. Examining sequencing treatments for distortion control. Tack weld high quality evaluation. Confirming a proper fit-up before Web Site welding. Checking the origin pass and succeeding weld passes. Inspecting the root condition before welding the opposite. Making sure that slag, silica, and other pollutants are eliminated between passes.
