Abstract
The invention relates to a method for connecting material webs disposed with overlapping edges, wherein an automatic welding machine having a driven chassis and a drive unit disposed thereon and a welding unit is guided along the overlap zone of the material webs to be connected, such that the carried welding unit connects the edges to be connected to one another. The invention further relates to an automatic welding machine for performing the method. The invention proposes that a temporary guide marking moving along with the chassis be generated along the edge of the overlapping material web by means of a marking unit disposed on the chassis, said guide marking always extending parallel to the edge and prescribing the path of the automatic welding machine on the overlapping material web and that the guide marking be detected by means of a sensor device during the movement of the automatic welding machine, wherein a control signal is generated for a display unit and/or the drive unit and the chassis is movable along the guide marking by means of the control signal.
