A method for producing a bipolar plate includes providing a first plate element and a second plate element. The first plate element has at least one bead with a longitudinal extent. The method further includes forming a welded connection between the first plate element and the second plate element along the longitudinal extent by using a laser processing beam. The formation of the welded connection includes detecting a geometric feature of the at least one bead located in a transverse direction. The geometric feature is a deepest point or a point of defined depth of the at least one bead. The formation of the welded connection further includes readjusting the laser processing beam in the transverse direction to a position of the detected geometric feature, and welding the first plate element and the second plate element together at the position of the geometric feature.
