Abstract: A spot welding head includes an electrical conductor guided into a tubular sheath whose ends are rigidly connected to rear ends of supporting bodies of several electrodes. The sheath defines a substantially stiff loop portion configured and arranged so as to be substantially parallel and to face an annular path defined by the electrodes and the supporting bodies, in such a way that two magnetic fields, one generated by electromagnetic induction caused by electric current flowing through the electric conductor placed into the loop-shaped sheath, and the other generated by electromagnetic induction caused by electric current flowing through the electrodes and the supporting bodies thereof, substantially cancel each other out or generate an overall magnetic field which is located forward of the rear end of the welding head or forward of the operator's body.

Abstract: A motor-vehicle, particularly an electrically-powered car of small size, has a supporting structure in the form of a reticular framework (2) of light alloy. The framework (2) includes two side structures (3) each formed by extruded profile elements (4) which are welded to joining knot elements (5) which have been obtained by casting. The side structures (3) are connected to each other by cross members (6, 7, 8, 9) which also are formed by extruded profile elements having their ends connected to the side structures (3) by mechanical coupling means, such as screws.
