In some cases, it might be necessary to test the WPS qualification by conducting examinations on weld promo codes (test pieces). Confirming the base metal and welding consumables conformity with the suitable specifications. Inspecting for joint tidiness and appropriate fit-up. Making sure that the joint style and weld preparation is certified with the WPS and suitable welding criteria (ASME, AWS, API).




Often, pre-welding evaluation may find irregularities that are within code limitations yet might position a concern at a later phase in production. That's why it's essential for the welding examiner to be accustomed to the whole production procedure and to be experienced with the welded tools. Assessment during the welding procedure is necessary for finding the weld issues and stopping an incorrect welding strategy from triggering massive weld beings rejected across the whole job.
