In some cases, it might be necessary to evaluate the WPS qualification by carrying out tests on weld vouchers (examination items). Confirming the base metal and welding consumables conformity with the suitable specifications. Inspecting for joint sanitation and appropriate fit-up. Making certain that the joint design and weld preparation is compliant with the WPS and applicable welding requirements (ASME, AWS, API).




Sometimes, pre-welding evaluation might find irregularities that are within code limitations but could pose a problem at a later phase in manufacturing. That's why it's essential for the welding inspector to be acquainted with the whole manufacturing process and to be experienced with the welded tools. Inspection during the welding process is vital for identifying the weld issues and stopping an inaccurate welding technique from creating enormous weld beings rejected throughout the entire job.
