I've got a MTB frame with a cracked weld, you can see grease pushing through in the below picture. I'm thinking about using a 30.9-27.2 seatpost shim as an internal reinforcing sleeve and JB Weld-ing it in place:


I talked to the manufacturer of the frame and they told me that it would be possible to weld, but I'd need to get it heat treated and honed afterwards, and the frame really isn't worth the expense. But it's worth it to spend $15 on a shim and a tube of JB, if it would hold up a decently long time.
