Abstract
The invention relates to a machining head with integrated powder supply for deposition welding using laser radiation. A machining head in accordance with the invention can in particular be used for deposition welding at a high deposition rate. In the machining head in accordance with the invention, the laser radiation is directed to supplied powder and to a material surface with a focal spot. The powder supply takes place symmetrically to the axial feed direction with a plurality of channels arranged oppositely. The channels are aligned at an obliquely inclined angle so that powder discharged from them is supplied into the focal spot of the laser radiation from two mutually oppositely disposed sides over the total width of the focal spot with respect to the axial feed direction.
