Welding AISI 1144/ASTM A-108 Resulfurized Steel
(OP)
Ok guys,
Welding AISI 1144 resulfurized steel... a.k.a. "Stressproof"
I'm aware of (some of) the implications of the sulfur content. Anyone out there had any good/bad luck welding this stuff?
Spec calls for a 3/8" fillet weld on an A-36 ring to be welded to a resulfurized 1144, 3 1/2" shaft...
My inclination is to go with E 7018 SMAW process with about 400ºF preheat.

Thanks BillPSU and Meteng,
We have had occasion in the past to "cobble" this stuff but this isn't a "just-get-me-by" fix.
The spec just caught up with the drawing. There is an ultra-sound, post-weld... Must be the customer has had some negative experience in the past.
Why would he still be hanging in there with this alloy...? (Oh, well...) Our past experience says there is no way to beat the inevitable... Russ
