Welding A36 to 304L
Welding A36 to 304L
(OP)
Guys,
I am considering an 8' diameter rotating cylindrical dryer that will have .375" 304L stainless shell near a burner and .375" A36 shell on either side butt welded together.
My concern is with the radial expansion of the two different metals at the butt joints. If the stainless expands much more than the carbon steel will that be enough to cause joint failures at the stainless to carbon joints? The maximum temperature the metals will see is approximately 800 deg. F.

With 8-ft in diameter and only 3/8" thick, your degree of restraint is very, very low.
