The present invention has as its subject a device for guiding and for transfer of at least two sheet metal blanks to be welded edge to edge. The device comprises, on the one hand, for each sheet metal blank, means (14a, 15a) for supporting the sheet metal blank along a horizontal reference plane and movable horizontally in the direction of a laser beam and means (14c, 15c) for vertical pressing of the sheet metal blank onto the support means and movable horizontally in synchronisation with the said support means for the movement by adherence of the sheet metal blanks and, on the other hand, means for maintaining in reference along a vertical plane the edge to be welded of one of the sheet metal blanks in the axis of the laser beam and means for placing under lateral pressure the edges to be welded of the two sheet metal blanks. The invention applies to installations for welding by laser beam sheet metal blanks of different geometrical shapes and/or of different thicknesses for example for the automobile industry.
