Automatic welding machine and method for thermal joining of material sheets

Abstract

An automatic welding machine for thermally joining sheets of material, in particular for edge-side joining of an overlapping upper material sheet to a lower material sheet, to be connected to one another in a materially bonded manner under the effect of heat and subsequent application of pressure, is provided comprising: a heating device for at least partially heating the material sheets to be joined in a connection region; a chassis comprising a pressure roller, configured to apply pressure to the material sheets in the working direction behind the heating device; a mount for one or more additional weights configured to increase a pressure on the pressure roller; and a weight sensor for measuring a weight force caused inter alia by the one or more additional weights in the mount, which acts at least partially on the pressure roller. Further a corresponding method is provided.
