Validating the base steel and welding consumables conformity with the applicable specifications. Inspecting for joint tidiness and appropriate fit-up. Making certain that the joint layout and weld preparation is certified with the WPS and applicable welding standards (ASME, AWS, API).




Sometimes, pre-welding examination may find abnormalities that are within code restrictions but can position a concern 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. Assessment during the welding procedure is essential for detecting the weld flaws and preventing a wrong welding method from creating enormous weld rejections throughout the whole project.
