Abstract
A method is described for manufacturing a built-up sheet panel by forming a double flanged joint with raised flange edges between sheets arranged alongside of each other, which are then welded together by means of a driven welding carriage, the raised flange edges being shortened in accordance with the invention shortly in front of the welding. A welding carriage suitable for this purpose is provided on its lower side, in front of a welding device as seen in the direction of travel, with a parting device which is preferably developed as driven pair of cutting rollers. In this way in particular thin sheets can be assembled with excellent quality to form a sheet panel.
Claims12
A method of manufacturing a built-up sheet panel comprising the steps of:
- locating sheet metal panels alongside of each other,
- forming a double flanged joint with raised flange edges between said sheet metal panels by feeding separate sheet metal edges relative to a welding carriage, said sheet edges being mated together but not welded prior to engagement by said carriage,
- guiding said welding carriage along the flange edges,
- welding said flange edges together by means of said welding carriage, and
- shortening the raised flanged edges shortly before effecting the welding.
Apparatus for manufacturing a built-up sheet panel from two sheet metal panels located alongside of each other, said apparatus comprising:
- means forming a double flange joint with raised flange edges between said sheet metal panels;
- a welding carriage;
- means for guiding said welding carriage along the flange edges;
- means for welding said flange edges together;
- and
- means for shortening the raised flange edges shortly before effecting any welding.
