- the fact of enclosing the internal reinforcing element in the axis parallel to the welding surface of the internal reinforcing element on the reservoir makes it possible to increase the contact surface between the armature and the element. internal reinforcement. This increase in surface thus limits the relative displacements between the two parts in the two parallel axes with respect in particular to the weld surface.
