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




Sometimes, pre-welding examination may find abnormalities that are within code constraints but can pose an issue at a later stage in manufacturing. That's why it's crucial for the welding inspector to be accustomed to the entire manufacturing procedure and to be experienced with the bonded tools. Inspection throughout the welding process is crucial for finding the weld flaws and preventing a wrong welding strategy from creating large weld denials throughout the entire project.
