A prompt inspection might avoid an entire batch of negative welds resulting from poor joint sanitation or fit-up.




Verifying the base metal and welding consumables compliance with the suitable requirements. Ensuring that the joint design and weld preparation is compliant with the WPS and suitable welding criteria (ASME, AWS, API).

Often, pre-welding assessment may find abnormalities that are within code limitations yet can posture a problem at a later stage in production. That's why it's important for the welding examiner to be familiar with the entire manufacturing process and to be experienced with the welded equipment. Evaluation during the welding process is necessary for detecting the weld issues and protecting against an inaccurate welding method from triggering huge weld denials throughout the entire project.
