Laserauftragsschweißen

Laserauftragsschweißen is a welding process that uses a laser beam as the heat source to melt and fuse filler material with a base material. The process is a form of additive manufacturing, where material is deposited layer by layer to build up a three-dimensional structure or repair a worn component. Typically, a laser beam is directed onto the workpiece, and simultaneously, a powder or wire feeding system introduces the filler material into the molten pool created by the laser. The molten material then solidifies, forming a new layer.

This technique offers several advantages, including high precision, minimal heat input, and the ability to weld a wide range of materials. The focused energy of the laser allows for precise control over the weld bead geometry and a reduced heat-affected zone, which minimizes distortion and preserves the material properties. Laserauftragsschweißen can be used for various applications, such as repairing high-value components like turbine blades or molds, adding wear-resistant coatings, and creating complex, customized parts. The process can be automated, leading to high repeatability and efficiency. Different laser powers and beam shapes can be employed to tailor the process for specific material combinations and desired outcomes.
