Since he said the elements were held together with screws I suspect that
the problem is actually the hole deformation anyway. Screws push
material from one tube into the other tube, making a kind of pseudo
rivet that remains even after the screw is removed. Drilling out the
hole might work.

Since aluminum tubing is thin and it has very high thermal

Ignacy-
Try heating the larger diameter tubing portion close to the joint
while simultaneously cooling the smaller diameter portion which is
telescoped inside of it.

I bought a 40m old beam that needs to be dismantled. With screws out the
elements do not move. Any idea what to do?
