RE: [MW:19923] Welding consumable for cladded plate SA516 Gr70 with SS316

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.

Regards, 

Ramon Briceno

Metallurgicla Engineer.

Dear Ramon Briceno,

 

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.

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,
