- - By Hojo (*) Date 09-25-2001 14:43
We have a project coming up requiring the welding of C-276 flanges to and Inconel 625 rolling. The flanges will be a slip-on type and will be approximately 2.5" thick. The Inconel body will be 3/8" in thickness.
Any idea of the correct filler metal to use. I believe it would be Inconel 625 but am not sure.

Alloy 625 weld electrode or filler (ENiCrMo-3 or ERNiCrMo-3) is acceptable. Alloy C-22 (ENiCrMo-10 or ERNiCrMo-10) or C-276 (ENiCrMo-4 or ERNiCrMo-4) may also be used.
