Abstract
For the manufacture of composite panels (16) it is proposed that they be held essentially upright by means of holding devices (17) and that welding by means of a laser welding plant (11, 13) be performed in this position. This affords a considerable space saving compared with the conventional horizontal arrangement in which the composite panels are processed and handled.
Claims19
Method for the manufacture of laser-welded tailored blanks from at least two sheet metal pieces, comprising the steps of:
- placing the at least two sheet metal pieces in a common plane in a generally upright position to weld facing edges of the at least two sheet metal pieces to form a composite panel;
- and
- processing the at least two sheet metal pieces while in the generally upright position, whereby the welding plane is generally vertical.
Apparatus for the manufacture of tailored blanks from at least two sheet metal pieces, comprising:
- a holding device for the at least two sheet metal pieces, the holding device being configured for operating in a generally upright position or being tiltable into a generally upright position for holding the at least two sheet metal pieces in a common plane in a generally upright position to weld facing edges of the at least two sheet metal pieces to form a composite panel;
- and
- a welding plant configured to generate a laser welding beam emitted generally horizontally with respect to the floor area of the holding device and the welding plant.
Method for the manufacture of laser-welded tailored blanks from, at least two sheet metal pieces, comprising the steps of:
- placing the at least two sheet metal pieces in a common plane in a generally upright position to weld facing edges of the at least two sheet metal pieces to form a composite panel;
- welding the at least two sheet metal pieces while in the generally upright position, whereby the welding plane is generally vertical;
- and
- oiling the composite panel while in the generally upright position.
Method for the manufacture of laser-welded tailored blanks from at least two sheet metal pieces, comprising the steps of:
- placing the at least two sheet metal pieces in a common plane in a generally upright position to weld facing edges of the at least two sheet metal pieces to form a composite panel;
- welding the at least two sheet metal pieces while in the generally upright position, whereby the welding plane is generally vertical;
- oiling the composite panel while in the generally upright position;
- and
- maintaining and storing the composite panel in the generally upright position.
Method for the manufacture of laser-welded tailored blanks from at least two sheet metal pieces, comprising the steps of:
- placing the at least two sheet metal pieces in a common plane in a generally upright position to weld facing edges of the at least two sheet metal pieces to form a composite panel;
- slipping the pieces by assistance of gravity to self-center and abut edges of the pieces;
- and
- processing the pieces while in the generally upright position.
