Patent ID: 8497447

Claim:
A production method for producing a sub-assembly consisting of a plurality of parts with a production system comprising a plurality of production installations arranged in series relative to one another, in a plurality of successive steps in which in the first production installation the parts received from a first parts delivery site in a first receiving region are conveyed along a first transport device to a first beam welding station with a first beam welding head, positioned relative to one another therein and clamped via a clamping system and welded together via beam welding, then conveyed to a first forwarding region from which a welded sub-assembly is transferred to the second production installation, in which at least one further part of the plurality of parts is received from a second parts delivery site and the previously welded sub-assembly is conveyed along a second transport device to a second beam welding station with a second beam welding head, positioned therein relative to one another and via a clamping system the further part of the plurality of parts and the previously welded sub-assembly are clamped and welded together via beam welding, after which another welded sub-assembly is conveyed to a further forwarding region, wherein welding radiation is supplied alternately from an energy source to the first and second beam welding heads of the first and second beam welding station and wherein within a first time interval, the parts of the plurality of parts are transported to the first beam welding station and the previously welded sub-assembly of the previous cycle is transported away from the beam welding station and during which in the second beam welding station the previously welded sub-assembly previously welded in the first production installation and a further part of the plurality of parts supplied from the second parts delivery site is clamped and welded to form the another welded sub-assembly and wherein within a second time interval in the first production installation parts of the plurality of parts are supplied from the first parts delivery site, clamped and welded to form the previously welded sub-assembly and during which in the second production installation the previously welded sub-assembly previously welded in the first production installation is transported to the second beam welding station of the second production installation and the another welded sub-assembly of the previous cycle welded in the second beam welding station of the second production installation is transported away to the second forwarding region.
