You may use E7018-1 for the CS part and 316 for the SS part. However you have to use a 309 barrier between CS and SS. If you mix 316 with CS you will get hot cracks

Dear Ramon
Sorry to say but your above providing information is not completely true.
i don't have t knowledge of piping welds but have well knowledge of ASME Sec VIII Div 1
as per UCS-56 you shall apply PWHT for a butt welds of more than 32 mm thickness ( if preheat is less than 95 Deg ) or more than 38 mm in any case . also all the butt welds shall be 100% radio-graphed for CS materials if thk exceed 32 mm as per UCS-57.
Thanks
Regards

- Dear Thuan,
All CS equipment fabricated by welding following a PWHT after the welding if the base material thickness is more than 25 mm by plate or 19 mm by piping. ASME Section VIII-UG Part give you information about the form that you can apply the PWHT.

Thank you so much for your information,
Yes, the ER-309 is intersection between CS Vs SS then after ER-316L for cladding..
How about PWHT for thickness over 30mm CS?

Dear Thuan,
According your requirement of cladding SA516-70 / SS316, begin the work of "buttering" with ER-309 filler to facilitate the microstructural transition between CS vs SS. This "buttering" can be 1 mm thickness and following use ER-316L filler to end up with 2 mm thickness. Use SMAW process, and depending of the cladding area to cover, change the aplication by SAW process, then you need a other welding material of common use in SAW process to joint SA516-70 / SS316L.

Ramon Briceno

Dear Expert ,
We have vessel shell plate A516-Gr 70 cladded with SS316 L, For the plate thickness: 25MM-40MM cladded 3mm.
Could you please advise the filler material selection and welding sequence for LS and CS.
I intend to use welding process FCAW and SAW. Or SMAW and SAW.
Thanks and Best regards,
