Validating the base steel and welding consumables compliance with the relevant requirements. Making certain that the joint layout and weld prep work is certified with the WPS and applicable welding standards (ASME, AWS, API).




Sometimes, pre-welding evaluation might discover abnormalities that are within code restrictions however could posture an issue at a later stage in production. That's why it's vital for the welding examiner to be aware of the whole production process and to be experienced with the bonded devices. Examination during the welding process is important for spotting the weld problems and protecting against an incorrect welding method from triggering large weld beings rejected across the whole task.
