| 摘要 |
The invention relates to a control and arrangement for continuous laser-welding of sheet or strip. Control means and an arrangement are described, by means of which sheets coated on one or both sides and having the same or different thicknesses and different or identical geometries (reflection) can be welded up at high weld quality, such as is applicable, for example, in car body construction. The sheets are here automatically aligned parallel to one another by mechanical means and contacted at their longitudinal edges to be welded up and the sheets are also length-centred by automatically operating control means. |
