Welding question - exhaust pipe

I need to cut this exhaust pipe to the left of the weld in this picture. How far back inside the outer pipe (left) would you guess that the weld travels. Hope to preserve part of the expanded section. Trial and error is an option, I reckon.

You will have to pull out the inner pipe. If it is stuck / rusted a bit of heat and a light hammer will work it out.

Weld metal does not "flow" into a joint like solder does, so the first post is correct.
Chop it right behind the weld.
