Abstract
A mobile road or rail tanker. The tanker is formed of sheet aluminum which forms an outer shell. The shell encloses a chamber which is divided by a transverse wall. The wall adjacent the shell comprises an annealed heat treatable weldable aluminum alloy which is relatively soft and ductile so that weld material adjacent the wall is stronger than the remainder of the wall.

- and
- wherein at least portions of said wall adjacent said shell comprise an annealed heat treatable weldable aluminum alloy which is relatively soft and ductile so that the weld material and adjacent wall portions are stronger than the remainder of the wall surrounding said adjacent wall portions.
