Patent ID: 11612953

Abstract:
The present invention relates to a method for reducing or completely closing an opening of an inner contour 2 of a workpiece by means of a material melted by a laser deposition welding device 7, comprising the following steps: providing a workpiece 1 with an inner contour 2 having an opening defined by an edge section 11, forming a plurality of base webs 41 from molten material by laser deposition welding by starting at the edge section 11 of the inner contour 2 of the workpiece in such a way that the formed base webs 41 protrude from the edge section 11 at a predetermined angle, connecting adjacent base webs 41 by forming connecting webs 42 from molten material by laser deposition welding in such a way that a support structure 4 which comprises base webs 41 and connecting webs 42 is formed, forming a cover layer 5 of molten material connected to the support structure 4 in such a way that the opening of the inner contour 2 is reduced or completely closed.
