摘要：
A process for the directional solidification of a weld seam during build up welding is provided which includes the targeted selection of process parameters for laser welding, feeding, laser power beam diameter, and powder mass flow. The temperature gradient substantially decisive for single crystal growth during laser application welding can be set deliberately.
