Sometimes, it may be essential to test the WPS credentials by conducting tests on weld promo codes (examination pieces). Confirming the base steel and welding consumables conformity with the applicable requirements. Inspecting for joint tidiness and correct fit-up. Making certain that the joint layout and weld preparation is certified with the WPS and suitable welding criteria (ASME, AWS, API).


Sometimes, pre-welding inspection may locate abnormalities that are within code restrictions but can present a problem at a later stage in production. That's why it's vital for the welding assessor to be acquainted with the entire manufacturing procedure and to be experienced with the welded equipment. Evaluation during the welding procedure is necessary for identifying the weld problems and avoiding an incorrect welding technique from triggering enormous weld rejections throughout the entire task.
