1. A machining and welding system for machining and welding ends of elementary panels with each elementary panel comprising a respective metal body having a respective two faces including a first face and a second face, the machining and welding system comprising:
a first support having a surface supporting a first of the elementary panels;
a second support having a surface supporting a second of the elementary panels;
a displacement device having a functional unit that is displaceable relative to the first and second support devices; and
a machining device connectable to the functional unit and configured to remove a thickness from at least one of the two faces of the first elementary panel mounted on the first support device, the machining device comprising:
a chassis;
at least two guiding members mounted on the chassis, the at least two guiding members being aligned along a horizontal reference direction and configured to guide a first face (F1) of the first elementary panel;
at least one machining tool mounted on the chassis and positioned between the at least two guiding members with respect to the horizontal reference direction and being displaceable, relative to the horizontal reference direction, in a vertical direction; and
at least one pressure member mounted on the chassis along the horizontal reference direction and configured to exert a pressure on a second face of the first elementary panel so as to press the first elementary panel against the at least two guiding members; and
a friction stir welding unit connectable to the functional unit to friction stir weld an end of the first elementary panel and an end of the second elementary panel together.
