<p>A device for welding motor-vehicle bodies which have been assembled loosely beforehand comprises at least one station (1) for welding the bodies (B), a conveyor line (2) for transporting the loosely preassembled bodies (B) to the station (1), and locating means (4) provided at the station for clamping the component parts of the body (B) in the correct positions for welding. The device also includes welding means (5) comprising a plurality of laser-welding torches (5) which are associated with the locating means (4) and are connected to one or more laser sources (S) by optical fibres (6). In a preferred embodiment, the device is applied to a flexible welding station in which the locating means (4) are carried by two or more pairs of locating frames (G) which can be interchaged rapidly in the working position. <IMAGE></p> |
