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




Sometimes, pre-welding assessment might find irregularities that are within code constraints yet can present a concern at a later phase in manufacturing. That's why it's crucial for the welding examiner to be accustomed to the whole production process and to be experienced with the bonded devices. Evaluation during the welding process is essential for detecting the weld flaws and stopping an incorrect welding strategy from causing massive weld denials across the whole job.
