The welds are really good, the nuts are even spot welded to the bolts so they cannot come loose. Unfortunately, they are too tight and the square "bones" can twist thus fatiguing the metal. I think she could have still been a standing doll if the joints weren't so tight. Fahhhhhk!
I thought I might've been able to loosen some joints up a bit, but since they're welded can't do that. There will be a gap between the mid-section cross piece and the section that broke off. I don't know how they can be re-attached.
The fix would have to be very strong since that area is highly stressed. Though if the joints were loosed in her hips and mid-section, It's possible the break might be repaired since it would no longer be highly stressed. I wouldn't mind if she were just a bed doll.

A possibility to remove the nut/bolt weld with a dremmel has occurred to me. I'd have to cut into the hips to get at those. I could try it with the mid-section swivel first. I'm pretty much resigned to the idea she won't be a standing doll anymore. This pic is the mid-section swivel/ bend joint.
