These records include Welding Procedure Specs (WPS), welder credentials, test documents, job specs, and applicable welding codes. A great CWI knows and understands the specs and code. After that, she or he ensures that the WPS and welder qualifications conform to those requirements. Prior to welding, CWIs check both base metals and filler steels, noting that they follow the WPS and job specs.


Throughout manufacture, CWIs check a range of things to guarantee that the WPS and task specifications are being properly adhered to. These items include interpass temperature levels, adequate fusion, cleansing, traveling speed, and weld deposit size. Evaluation throughout welding is often overlooked, however it is an essential part of guaranteeing weld quality.

After a weld is completed, a CWI visit our website will inspect it closely, inspecting and determining any type of suspensions such as porosity, undercut, splits, insufficient blend, or poor account. The dimension of the weld is likewise measured for conformance to the project specifications. If any of the discontinuities do not follow project needs, they are taken into consideration issues and need to be repaired.

Verifying the base metal and welding consumables compliance with the appropriate specs. Making sure that the joint layout and weld prep work is certified with the WPS and suitable welding requirements (ASME, AWS, API).




Sometimes, pre-welding inspection might discover irregularities that are within code constraints however could pose a concern at a later stage in production. That's why it's essential for the welding examiner to be acquainted with the whole production procedure and to be experienced with the bonded equipment. Examination during the welding process is necessary for finding the weld defects and protecting against a wrong welding method from causing large weld rejections throughout the entire task.

Another example would certainly be not inspecting for extreme distortion, which would certainly result in weld being rejected and costly rework if done on expensive devices like warmth exchangers, distillation columns, and boilers. A few of the typical quality assurance checks during welding are: Confirmation of pre-heat and interpass temperature levels and ensuring that they are within limits specified in the WPS.


Verify the securing gas and flux are as instructed in the WPS. Examining sequencing treatments for distortion control. Tack weld top quality evaluation. Confirming a correct fit-up prior to welding. Inspecting the root pass and successive weld passes. Inspecting the origin problem prior to welding the other side. Making sure that slag, silica, and various other contaminants are eliminated in between passes.
