Validating the base steel and welding consumables conformity with the suitable specifications. Making sure that the joint layout and weld preparation is certified with the WPS and suitable welding requirements (ASME, AWS, API).




Sometimes, pre-welding inspection may find abnormalities that are within code restrictions but can position an issue at a later phase in production. That's why it's essential for the welding examiner to be aware of the whole production procedure and to be experienced with the welded tools. Evaluation during the welding process is important for detecting the weld problems and preventing a wrong welding approach from creating huge weld denials across the whole project.

Some Known Questions About Aws Cwi.

An additional example would be not inspecting for extreme distortion, which would result in weld being rejected and pricey rework if done on expensive devices like heat exchangers, distillation columns, and boilers.
