| Abstract Scope |
Additive manufacturing by means of laser metal deposition (LMD) of metals holds high application potential due to the simple process scaling with regard to the production of large and complex three-dimensional structures. One of the central process variables to be considered is the component heat. The thermal energy supplied by a laser during the manufacturing process leads to different temperatures on the surface to be welded. This can lead to deviating welding results with otherwise constant process parameters. The investigations aimed at in this work shall contribute to the understanding of the influence of the substrate/part heat on the LMD process result and bring solutions for the correction of possible deviations of the welding result. For this purpose, individual weld tracks with different process parameters on substrates with controlled temperature levels will be produced and analyzed to formulate a model for the prediction of the weld result. |
