How can we weld a clad material to inconel 625? 1

[mirhosseini]

Hi to all !
this is my first question!!

We want to weld API 5X, clading by Inconel, to Inconel 625 and used filler metal is Er NiCrMo3.
We have a PQR for Inconel to Inconel and used filler metal is Er NiCrMo3.
I think if I have a PQR for API 5X to API 5X with used filler metal Er NiCrMo3, then I can cover my WPS with these two PQRs. Am i Right? if not please tell me how we can cover my WPS.
If, howeve, these two Cover my WPS is there another methode that I cover my WPS?

Thanks

Regards

Assuming you are qualifying to ASME Section IX, you will also need to qualify the API 5LX to 625 Alloy or any other alloy in P No. 43 using E/ERMiCrMo-3 or any other filler metal in Group F43.
