Verifying the base steel and welding consumables compliance with the relevant specs. Guaranteeing that the joint design and weld prep work is certified with the WPS and relevant welding criteria (ASME, AWS, API).




In some cases, pre-welding inspection may discover abnormalities that are within code constraints yet could position an issue at a later phase in production. That's why it's essential for the welding inspector to be acquainted with the entire production procedure and to be experienced with the welded equipment. Examination during the welding procedure is crucial for detecting the weld issues and preventing an incorrect welding approach from causing large weld rejections across the whole project.
