Confirming the base steel and welding consumables conformity with the applicable specifications. Guaranteeing that the joint layout and weld preparation is compliant with the WPS and suitable welding criteria (ASME, AWS, API).




Occasionally, pre-welding evaluation may locate abnormalities that are within code constraints yet can pose a concern at a later stage in production. That's why it's important for the welding inspector to be acquainted with the whole production process and to be experienced with the bonded devices. Inspection throughout the welding process is important for spotting the weld issues and protecting against an inaccurate welding approach from creating large weld rejections throughout the entire project.
