NO. You need to re qualify the WPS, as the F no is different.

Dear Experts,

 

   We have material LTCS CLADDED WITH B423 UNS N08825  and have approved WPS and PQR using Filler ERNICRMO-3 for GTAW in Root and Hot Pass and electrode ENICRMO-3  for SMAW in  Filling and Cap.

 

so, the question is , can be used another supporting PQR For CARBON STEEL (using Filler ER70S-3 in Root and Hot Pass and electrode E7018-1  for Filling and Cap )to produce WPS using Filler ERNICRMO-3 in Root and Hot Pass and electrode E7018-1  for Filling and Cap, due to shortage in ENICRMO-3.          

Any troubles may be happened regarding dilution or what

 

Waiting your scientific  and specific reply.

 

Thanks

Mohamed
