Identification of welders qualification for every WPS to be used and also all welder certification certifications stand. Welding consumables to be used are-as specified by the WPS-stored/controlled as defined by the QC procedure. Joint fit-ups remain in accordance with WPS/ illustrations Tack welds are acceptable per requirements, code or WPS.
