Abstract
In a device for welding structures, such as motor-vehicle bodies or parts thereof (for example, sides), constituted by loosely preassembled, pressed sheet-metal elements, a station for welding the elements includes two rotary drums for rapidly changing the frames for positioning the elements to be welded in the operative position, according to the type of structure to be welded. The various positioning frames are rotated by rotors and guided on annular tracks on each rotary drum. A sector of each annular track can be separted and moved along a line transverse the conveyor line for the structures to be welded in order to bring a certain positioning frame into the operative position.
