What this is about, is I'm building slip rolls & the 1/2" mild pieces
are the ends & the SS are the bottom mounting plates (they're SS only
because that's what I had). The forces on the welds will be from my
pulling on the roll lever. Not that much, but if the welds were
brittle, say, it'd be a pain to rebuild it.
What I've heard here & Googling the archives is that SS rod is really
the way to go. But I did a test - welding up the same material. I put
about 3/4" of bead on each side & a bead across the end (1/2"). I
welded a 24" piece of 1" bar to the 1/2" plate, for leverage.
To test it I put the SS plate in the vice & pulled on the 1" bar
(actually, I supported my 190lbs on it). As far as strength - no
problem, I probably put 400 - 600 lbs tension on it. As far as the
brittleness, I took a rBFG (6lb sledge) & beat on it - no problem. When
I took the test apart I cut the weld on one side & bent the piece back
over the weld on the other side. That weld broke in the middle of the
bead (did not tear out of either piece).
I don't doubt that SS rod is the proper way to go & in a commercial
situation that's what I'd use. But in this HSM context, I'm going with
