A welding station (1) for motor-vehicle bodies (3) comprises a conveying line (2) for conveying the bodies (3) to be welded and at least one pair of side frames (5) for referencing and clamping of the parts to be welded, arranged at the two sides of the line (2) and displaceable in a direction transverse to the line (2) between an open position and a closed position. In their movement from the open position to the closed position, the two side frames (5) also cause raising of a bottom frame (11), via cam means (12,13), in such a way that the body (3) to be welded is taken up by said bottom frame (11) and raised with respect to the conveying line (2). In said raised condition, the body is referenced and clamped by devices for referencing and clamping carried by the two side frames (5) so as to enable welding of the various parts of the body (3) in the correct position of assembly. Once welding is completed, the two side frames (5) are re-opened, thus causing also lowering of the bottom frame (11) and consequent deposit of the welded body (3) on the conveying line (2), which brings about exit of the welded body (3) from the welding station (1).
