Abstract
A device for the simultaneous welding of work pieces and containing a plurality of laser light sources. The laser light sources are positioned on at least one circle in such a manner that the partial beams emitted by the laser light sources produce at least one region that lies radially further inwards. The region, in some areas, has a substantially constant luminosity and the work pieces are introduced into the region.
Claims9
An apparatus for simultaneous welding of work pieces, the apparatus comprising:
- a plurality of laser light sources outputting laser beams having beam elements, said laser light sources disposed in a formation defining at least one circle and said beam elements emitting from said laser light sources producing an area disposed radially further inwards having an energy density being substantially constant in places, and into said area the work pieces being introduced;
- at least one first mirror element disposed radially further inwards than said at least one circle on which said laser light sources are disposed, said at least one first mirror element reflecting at least some of the beam elements in an axial direction;
- and
- a device for varying an axial distance between said first mirror element and at least one of the work pieces.
