I haven't been able to find yet in my searching exactly what i'm looking for, I am trying to determine what factors I should consider in designing a weld between A36 and 304 SS. I have a welded connection between a pipe and blind flange, both currently A36 steel, using E70XX weld rod, which has performed well for us for years. I am changing the flange to 304 SS to bolt to another stainless plate, so I will need to change the filler material to E309 because of the dissimilar metals, but is there any reason to assume that this weld will be any weaker than the original weld?
Thanks for the help!
