Abstract
(A1) Beim Auffuellen von Vertiefungen (16) mittels Schweissen koennen Anbindungsfehler und Risse auftreten. Durch eine geeignete Fuellstrategie, bei der Schweissmaterial auch aus der Vertiefung (16) heraus auf die Oberflaeche (13) erzeugt wird, werden diese Probleme vermieden.
DE 102009016260 A1 UPAB: 20101022 NOVELTY - The method comprises filling a recess (4) through welding seam, where the recess has a contour that limits the recess against an external upper surface of a component (1, 120, 130, 155). The welding seam is laid so that the welding seam arrives external of the contour of the recess on the surface. The first welding seam corresponds in its form of the contour. The second welding seam is produced within the first welding seam that corresponds to the contour. The filling of the recess is carried out within the first or second welding seam in meander-shaped manner. DETAILED DESCRIPTION - The method comprises filling a recess (4) through welding seam, where the recess has a contour that limits the recess against an external upper surface of a component (1, 120, 130, 155). The welding seam is laid so that the welding seam arrives external of the contour of the recess on the surface. The first welding seam corresponds in its form of the contour. The second welding seam is produced within the first welding seam that corresponds to the contour. The filling of the recess is carried out within the first or second welding seam in meander-shaped manner. The first layer completely covers the recess by the welding web, where the welding layers are used to fill the recess. The main direction of the welding web passes vertically to each other in an angle of 0-90 degrees . The welding seam is transferred to the welding layer in meander-shaped manner. The further welding layers partially or completely cover in its direct predecessor. The recess comprises flanks that pass vertically to the surface of the component. An INDEPENDENT CLAIM is included for a method for the heat treatment of a welding seam. USE - Method useful for welding a component by laser cladding. ADVANTAGE - The method ensures simple welding of a component with good weld quality.
