The primary objectives of weld inspection and high quality control are protecting against welding issues by taking corrective activities early on in the manufacturing phase, and making sure the quality of completion product. A timely assessment might stop a whole set of poor welds resulting from bad joint sanitation or fit-up.




In some cases, it may be required to test the WPS qualification by performing examinations on weld vouchers (test pieces). Confirming the base steel and welding consumables conformity with the applicable specifications. Inspecting for joint cleanliness and correct fit-up. Ensuring that the joint style and weld preparation is compliant with the WPS and suitable welding standards (ASME, AWS, API).




Often, pre-welding examination might find abnormalities that are within code restrictions however can pose a problem at a later stage in manufacturing. That's why it's important for the welding assessor to be aware of the whole manufacturing procedure and to be experienced with the bonded tools. Evaluation throughout the welding procedure is necessary for detecting the weld issues and avoiding an incorrect welding approach from causing large weld rejections throughout the whole task.
