如今，大多数技术零部件均由整体材料制成。然而，以前使用的整体材料达到了其技术和结构极限，因此可以通过混合部件来实现部件性能的改进。将先前连接的半成品锻造成净形状混合部件是一种通过几个工艺步骤生产功能性改装零件的有前景的方法。与其他制造技术相比，这种新的工艺链具有许多优势。例如，生产具有高材料利用率的特定负载适应锻件、通过后续成型工艺改进连接区域以及由于半成品的简单几何形状而易于实施连接工艺。本文描述了混合钢零件的生产工艺，该零件是通过沉积焊接工艺与随后的热锻（镦粗）或楔横轧相结合来生产的。可以证明，创新的工艺链能够生产混合零件，从而通过锻造工艺改善激光沉积材料的机械性能。
Today most technical parts and components are made of monolithic materials. Nevertheless, the previously used monolithic materials reach their technological and constructive limits, so that an improvement of the component properties can be realized by hybrid parts. Forging of previously joined semi-finished products to net shape hybrid components is a promising method to produce functional adapted parts in a few process steps. This new process chain offers a number of advantages compared to other manufacturing technologies. Examples are the production of specific load-adapted forging parts with a high level of material utilization, an improvement of the joining zone caused by the followed forming process and an easy to implement joining process because of the simple geometries of the semi-finished products. This paper describes the production process of hybrid steel parts, which are produced by a combination of a deposition welding process with a subsequent hot forging (upsetting) or cross-wedge-rolling. It could be shown that the innovative process chain enables the production of hybrid parts whereby the forging processes lead to an improvement of the mechanical properties of the laser deposited material.
