Welded Patch Repair question

I know you said you got it, but I figured out how to make some changes
in the program and wonder it it shows up now:
-------------
You should use the next diameter of tube to get easy conformation the
the shape of the tube you are repairing. But, if you have no choice but
to use a patch from
the same diameter tube, there is no problem with heating the patch to
make it plastic enough to conform to the outside contour of the tube
being repaired. If it
doesn't lay down smoothly you can tack welt the patch where it makes
contact with the tube, then heat the patch with the torch and gently tap
it into place, till it lies
down tightly with the tube, with a small hammer. You can tap and tack as
you go until the patch is a tight fit, the weld it.

If you want to make a slip over repair using a whole piece of tube, you
will have to use the next diameter tube as it would be virtually
impossible to expand the
diameter of a tube uniformly and continuously around its circumference.
