These records consist of Welding Procedure Requirements (WPS), welder qualifications, test documents, task requirements, and applicable welding codes (https://trello.com/u/awscw1w3lding/activity). Prior to welding, CWIs examine both base steels and filler metals, keeping in mind that they comply with the WPS and job requirements.


During fabrication, CWIs examine a range of items to make sure that the WPS and project specs are being appropriately followed. These products consist of interpass temperatures, adequate combination, cleansing, traveling speed, and weld deposit dimension. Inspection during welding is occasionally overlooked, however it is an essential part of making certain weld quality.

The 2-Minute Rule for Aws Cwi

After a weld is finished, a CWI will certainly inspect it closely, inspecting and gauging any kind of discontinuities such as porosity, undercut, cracks, incomplete fusion, or inadequate profile.

Validating the base steel and welding consumables conformity with the relevant specifications. Guaranteeing that the joint design and weld preparation is compliant with the WPS and applicable welding standards (ASME, AWS, API).




Sometimes, pre-welding inspection might discover irregularities that are within code limitations yet might pose a problem at a later stage in manufacturing. That's why it's essential for the welding examiner to be acquainted with the whole manufacturing process and to be experienced with the bonded devices. Evaluation during the welding process is important for spotting the weld issues and protecting against an incorrect welding approach from creating large weld rejections throughout the entire task.

An additional example would certainly be not checking for too much distortion, which would lead to weld denial and costly rework if done on expensive devices like heat exchangers, purification columns, and central heating boilers. Some of the common quality assurance checks during welding are: Confirmation of pre-heat and interpass temperature levels and making sure that they are within limits specified in the WPS.


Confirm the securing gas and flux are as advised in the WPS. Assessing sequencing procedures for distortion control. Tack weld quality examination. Confirming a proper fit-up before welding. Checking the root pass and successive weld passes. Checking the root condition before welding the opposite. Ensuring that slag, silica, and various other contaminants are removed between passes.
