Welding tools remains in ideal problem and also adjusted as proper.

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

The minimum temperature for Preheat (if needed) remains in conformity with WPS.
