Question on welding stainless to carbon steel
(OP)
My first time post and I need the weld spec for stainless to carbon. I'm the mechanical superintendent for a water/waste water company. The process we are using is
GTAW with 309 filler. The engineering firm who supports us
stated they have never seen this done. I am aware this is the proper procedure, I would just like the procedure in hand to better present my case. Any help would be appreciated. My e-mail is dharper10@cox.net.
Thank you
Dennis Harper

See my post in Thread725-107465 "Welding Stainless Steel 316 to Carbon Steel." I posted a procedure for P-1 to P-8 with GTAW.

You may use filler as ijzer's comment. However, please also consider the application of carbon steel at such service temperature.
Carbon steel maximum operation temperature

If it is butt joint welding , it is better to complete weld with ER NiCr-3
