Subject: Welding mild steel to
I am designing a steel window frame, about 8' wide by 6' tall, with a steel
frame and 3 interior vertical mullions that divide it into 4 window sections.
It will be encased in 44 pieces of carved limestone mortared together and
connected with stainless steel pins epoxied into holes drilled in the
limestone, per the manufacturer's typical details. We are considering
using stainless steel for the 3 interior mullions, and perhaps for some other
parts of the frame, to avoid rusting. I have a couple of questions:
How should the stainless steel be specified?
Can mild steel and stainless be welded together? Any special requirements
for that welding?
If we wanted to hot-dip galvanize the mild steel would it be a concern that
part of the assembly is stainless? Is stainless compatible with
I'm assuming that stainless is at least as strong as A36 steel, so I'm using
that as the basis of my design. Is that reasonable?
This isn't a hugely critical structural, but we would prefer that it not rust
for a few decades.
Thanks very much for your help.
