Hi,
You can not weld Titanium to Stainless steel by conventional arc welding process. If to be welded by arc welding process using Copper as Interlayer or a transition material. It would involve expensive R&D work. The other option is to is to perform solid state welding (Friction Stir Welding), which would not be possible for the component in question.
What's the technical rationale behind choosing 316L Piping and Ti Gr-2 as flange?? Why the flange can't be of identical 316L, same as the piping material?
Thanks.
