Integrally-formed welding structure for connecting and laminating grid assembly

The utility model discloses a grid assembly lamination integrated forming welding structure comprising a cell sheet, the upper side and the lower side of the cell sheet are respectively provided with an electric insulation optical transparent film layer, the outer side of the electric insulation optical transparent film layer is bonded with a plurality of welding strips which are uniformly distributed at equal intervals, and the welding strips are arranged on the upper side and the lower side of the cell sheet. The surface of the solder strip or one side close to the electric insulation optical transparent film layer is coated with an alloy coating. According to the utility model, the surface of the welding strip or one side close to the electric insulation optical transparent film layer is coated with the alloy coating, and after lamination, the alloy coating on the surface of the welding strip is slightly softened and wets the cell sheet, thereby forming ohmic contact and completing alloying. The welding st
