Dear Vaibhavi
Please see comments on WPS/PQR review texted below,
1.Nitrogen is not preferred as a backing/purging gas.This may increase hardness of weld/HAZ and more precautions may be necessary while using Nitrogen.Recommend Argon for purging.
2. Lifting lugs are not covered in the weld map.
3. Welders used to qualify procedures may be used to perform production welds provided they are in frequent touch with the welding processes used in the welding procedures.
3.Welders used are qualified only in 1G position.Any other position shall require seperate welder performance qualification.
4. What about weld map for weld joints in motor top assembly drawing(N1 to N6 nozzles etc.)?? kindly upload.
