Abstract
A welding station, for example for welding motor-vehicle bodies, receives only a part of the structure to be welded from a conveyor line, the remaining components of the structure being assembled with said part at the welding station itself, by using two locating gates which receive said components from manipulating robots, said robots also providing for carrying out the spot welding of the structure once the latter has been assembled and locked in a proper welding position by said locating gates. The locating gates are provided with self-propelled lower trolleys guided on rails, in order to be rapidly interchanged with another pair of locating gates adapted to a different type of body.
