Dear Friends
Applicable Code – ASME Sect IX-2007
Weld Process - SMAW
Consumable used - ENiCrMo-3.
Existing PQR qualified with Incoloy 825 to Incoloy 825 & Incoloy 825 to Corten A , both is using above grade electrode.

Please advise me whether above WPS/PQR can it be applied to welding

1 - Incoloy 825 ( P No ; 45 ) to SUS316L ( P No.
2 - Incoloy 825 ( P No ; 8 ) to Carbon Steel [ Eblow ASTM 234 ]( P No ; ASTM A131 Group 1).
Based on QW-423.1- seems possible.

Also please advise cautions/precautions required as well

Appreciate all inputs.

Thanks

No, please refer QW424, you need new qualification for the combinations
QW423 is applicable for performance
