Abstract
A device for welding motor-vehicle bodies which have been assembled loosely beforehand comprises at least one station for welding the bodies, a conveyor line for transporting the loosely preassembled bodies to the station, and locating means provided at the station for clamping the component parts of the body in the correct positions for welding. The device also includes welding means comprising a plurality of laser-welding torches which are associated with the locating means and are connected to one or more laser sources by optical fibres. In a preferred embodiment, the device is applied to a flexible welding station in which the locating means are carried by two or more pairs of locating frames which can be interchanged rapidly in the working position.
