ABSTRACT:
A method for producing a seal-welded connection between a stamped grid designed to conduct electricity and embedded in a laser-transparent plastic, and a plastic component positioned underneath the stamped grid, using a laser method, including the following method steps, executable in any order: a) carrying out a first welding operation by emitting laser beams, the laser beams falling on the surface of the stamped grid embedded in the plastic, at an angle α, and the angle α being inclined in a positive direction with respect to the vertical; and b) carrying out a further welding operation by emitting laser beams, the laser beams falling on the surface of the stamped grid embedded in the plastic, at an angle α, and the angle α being inclined in a negative direction with respect to the vertical.
