Acceptable with below note : Ensure A NO  1 is met as Mn and Si are permitted higher  in SFA 5.18 for ER 70S-6  On Sat, 10 Oct 2026 at 7:36 PM, Noble < noblejohny94@gmail.com > wrote: Dear Experts, If a PQR is qualified using ER70S-2 with impact testing, can we use the same PQR to prepare a WPS using ER70S-6, since both filler metals fall under the same F-Number and A-Number?

Your expert opinions and code references would be appreciated. -- https://materials-welding.blogspot.com/ https://www.linkedin.com/groups/122787 --- You received this message because you are subscribed to the Google Groups "Materials & Welding" group.
