Validating the base steel and welding consumables conformity with the appropriate specifications. Making sure that the joint style and weld prep work is compliant with the WPS and applicable welding criteria (ASME, AWS, API).


Often, pre-welding evaluation might find abnormalities that are within code constraints but could present a problem at a later stage in production. That's why it's essential for the welding assessor to be accustomed to the entire manufacturing process and to be experienced with the welded devices. Inspection during the welding procedure is vital for detecting the weld flaws and stopping an incorrect welding method from creating enormous weld rejections throughout the entire project.
