Abstract
Official abstract text for this publication.
An oscillating welding method is provided. The oscillating movement during welding in the vertical and/or horizontal direction results in smaller grains being obtained, the smaller grains preventing the development of cracks during welding.
First claim
Opening claim text (preview).
1 . A welding method comprising: moving an energy source for welding and/or a material feed so as to oscillate with respect to a surface of a substrate. 2 . The method as claimed in claim 1 , wherein remelt welding takes place. 3 . The method as claimed in claim 1 , wherein deposition welding takes place. 4 . The method as claimed in claim 1 , wherein the energy source is moved so as to oscillate in a vertical direction with respect to the surface. 5 . The method as claimed in claim 1 , wherein the energy source is moved so as to oscillate in a horizontal direction with respect to the surface. 6 . The method as claimed in claim 1 , wherein the energy source and the material feed are moved so as to oscillate horizontally with respect to the surface of the substrate. 7 . The method as claimed in claim 1 , wherein an oscillating motion in a vertical direction of the energy source and the material feed takes place. 8 . The method as claimed in claim 1 , wherein laser radiation is used as the energy source. 9 . The method as claimed in claim 1 , wherein a powder is used as a material, which is fed through the material feed. 10 . The method as claimed in claim 1 , wherein nickel- or cobalt-based superalloys are used as the substrate. 11 . The method as claimed in claim 1 , wherein a welding nozzle is used, the welding nozzle having the material feed and generation and supply of energy. 12 . The method as claimed in claim 1 , wherein the oscillating motion is up to 2 mm. 13 . The method as claimed in claim 1 , wherein a welded area is greater than or equal to 4 mm in at least one orientation. 14 . The method as claimed in claim 1 , wherein a plurality of welding beads are generated or deposited next to one another. 15 . The method as claimed in claim 1 , wherein the material feed is a powder feed, and the energy source is laser radiation. 16 . The method as claimed in claim 12 , wherein the oscillating motion has a deflection between 1 mm and 2 mm.
