Recognition of welders certification for each WPS to be made use of as well as all welder qualification certifications stand. Welding consumables to be made use of are-as specified by the WPS-stored/controlled as specified by the QC treatment. Joint fit-ups are in conformity Visit This Link with WPS/ illustrations Tack welds are appropriate per requirements, code or WPS.

The minimum temperature for Preheat (if called for) is in conformity with WPS.
