Welding Cu-Ni tubes to SS tube-sheet

[rmw]

Any forum members have any experience with welding Cu-Ni (preferably 90-10) tubes directly to a SS tube-sheet without any overlay material, any grade of SS but especially 304 or 316? And yes, I did a search on this site but came up with nothing (one thread that was about expansion).

Thanks,

No, sorry, I should have been more specific; arc welding, autogenous or filler metal, manual or orbital.

Have you checked the American Welding Society site?
