hmmm.....

my idea was to take out about 1" of the failed tube and fishmouth(spelling?)
both open ends. Inserted tube (with about twice wall thickness) is visible
and can be welded in. How's about this?

found a tube which fits inside the failed tube, but how can I weld it in
then - just asking

The ends of the insert are tapered. Holes are drilled in the failed tube
to allow rosette welds of the interior tube, which have much the same
effect as through bolts, but rather lighter and stronger, if well done.
