     I think you would be better off welding a conformable patch on the pipe.

I have thought about a conformable patch, my concern there is that perhaps the weld bead itself would be a stress point. I use a TIG welder with the appropriate  rod for the material, so maybe I'm
worrying too much, if that is possible.
