I think it depends on what you're doing. If the OP is looking just to make some brackets or do some light repair that's fine. If he want to get into anything structural, load bearing, and other higher end areas I would strongly suggest school. Studies in metallurgy I'd also recommend.
I think it just depends on what level he wants to get to.
Edit: A good cheap starter book on the subject.
