摘要： A method of material processing is disclosed, the method comprising applying a laser beam (5), directing the laser beam (5) to a processing location (6) to melt material (3) at the processing location (6), and providing a shielding gas flow (8). The shielding gas flow (8) is controlled dependent on at least one of a processing location (6) position, a processing advance vector, and a processing trajectory.

摘要： The invention refers to a method for manufacturing a three-dimensional metallic article/component made of a Ni-, Co-, Fe- based superalloy or combinations thereof, entirely or partly, by a powder based additive manufacturing process. During the step of performing powder melting by scanning a dual laser setup is used, where two laser beams of different beam properties are combined in the same machine and by adjusted beam profiling and integration of a suitable beam switch in a controlled manner a switching between two different laser beam diameters is performed. In each layer the laser beam with the smaller diameter scans the whole area and in every kth layer, with k>1, the laser beam with the larger diameter scans the area where a coarse grain size is needed thereby remelting the area with fine grain sizes. With such a manufacturing method higher lifetime and operation performances of metallic parts and prototypes can be reached.
