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




Confirming the base steel and welding consumables conformity with the relevant specifications. Guaranteeing that the joint style and weld preparation is compliant with the WPS and appropriate welding requirements (ASME, AWS, API).




In some cases, pre-welding evaluation might locate irregularities that are within code limitations yet might position an issue at a later phase in production. That's why it's essential for the welding assessor to be knowledgeable about the entire manufacturing process and to be experienced with the bonded devices. Evaluation throughout the welding process is essential for detecting the weld problems and preventing a wrong welding technique from causing massive weld beings rejected across the whole project.
