Recognition of welders qualification for each and every WPS to be made use of and all welder certification certificates stand. Welding consumables to be used are-as specified by the WPS-stored/controlled as specified by the QC treatment. Joint fit-ups are in accordance with WPS/ illustrations Tack welds serve per standards, code or WPS.
