Got news for you, Nil, "butted" tubing is thicker on the ends.

It's pre stressed to overcome tensile loading!

All the stresses were relieved when it broke. It's still broke.

Since you can't afford to live in a trailerpark that "repair" is the
trailerboat squatter equivalent of a junk car in the yard.
