Output (English): The joining of the two surface sts (1, 5) is created under their two edges (3, 7), which coincide with at least one joint and contains at least one of the square p's. other means (9) select the edges (3) of the first face (1) behind the edge (7) the type of face (5) into the face shapes in the face of the face (5) and engaging the shapes in a backward-looking manner, viewed from the edges, into the n (13), into which the shape of the surface (5) is inserted for inserting shapes adding it to the expanded end of it with a solid device (9). It also includes at least one securing element (17, 19) to select the edges (3) of the first (1) to match the selected type (5), which is shifted to the side with respect to ° C. The device (9) and which fits into the surface of the surface (5) is secured against opening with a spreading hole of its height (13). It is only the joint, or at least the welded fastening means, to the at least one edge (3, 7) of the joining surfaces (1, 5). The two surfaces to be bonded (1, 5) are made of steel plating and the above-mentioned weld fixing means are made up of two laser dot welds (25) formed by a laser beam. When the joining surface is pushed into one another, the engaging protruding elements are inserted into the recesses in a mechanically interlocking manner, with the surfaces being welded together with the laser points together with the corresponding welding fasteners. welds.
