Something Richard Sohn told me, and I soon after found to be
VERY true.
The HAZ of stainless weldment will rust almost as easily as
mild steel
if not properly treated. It must either be buffed to the
original
shine, passivated/pickled, or painted. Since you won't have
access to
the inside of the tube, going stainless may not get you
much.
Hi
Ernest,
I can't say I've ever
heard of, or thought about this problem. I know that the weld will
carbonize (I think that's the correct term) if air is allowed to contact the
weld before it cools a certain amount, and shielding gas can be used inside the
tube. Would this prevent the rusting you're talking
about?
I actually have two thoughts on the
mount. One would be using square tubing, and the other is just using
angle. The angle would allow me to weld, bolt, or do both. It also
gives a nice flange to bolt to without concern for crushing a tube. You can hang
lots of engine stuff off of that flange if needed, so it's pretty convenient as
well.
Thanks,
Rusty
