Abstract
Official abstract text for this publication.
Provided are build-up welds which are achieved by means of a targeted frequency selection and an amplitude which relates to the diameter of the energy beam.
First claim
Opening claim text (preview).
1 . A method for build-up welding having an oscillating solidification front, in which an energy beam, oscillates, wherein the energy beam oscillates at a frequency of 20 Hz to 50 Hz, and an amplitude of the oscillation is between 35% and 65% of diameter of the energy beam at machining location. 2 . The method as claimed in claim 1 , wherein the powder build-up welding laser powder build-up welding. 3 . The method as claimed in claim 1 , wherein a component from a nickel-based or cobalt-based super alloy is build-up welded. 4 . The method as claimed in claim 1 , wherein the diameter of the laser radiation at the machining location is 500 μm to 1200 μm. 5 . The method as claimed in claim 1 , wherein an advancement speed is between 400 mm/min and 600 mm/min. 6 . The method as claimed in claim 1 , wherein the energy beam oscillates at a frequency of 35 Hz. 7 . The method as claimed in claim 1 , wherein the amplitude of the oscillation is 50%. 8 . The method as claimed in claim 1 , wherein the machining location is a focal point. 9 . The method as claimed in claim 4 , wherein the diameter at the machining location is 600 μm to 800 μm. 10 . The method as claimed in claim 5 , wherein the advancement speed is between 500 mm/min.
