由于功能紧凑化的趋势，小型化在工业生产中变得越来越重要。这使得在各种条件下的混合接头也在微观范围内是必要的。现有的连接解决方案通常由于连接原理而具有限制。因此，本文提出了一种基于激光诱导冲击波塑性变形的微尺度高速成形新方法。首先，它显示了如何金属板片接头可以实现这种方法。利用所产生的接头进行拉伸测试，其中可以实现26.7N的最大剪切力。为了更详细地了解过程，测量了TEA-CO2激光诱导冲击波的作用压力的近场。此外，它是确定的TEA-CO2激光诱导等离子体出铝的燃点是约8毫米以上的表面。
Due to an ongoing trend of function compaction miniaturization gets more and more important in industrial production. This makes hybrid joints under various conditions also in the micro range necessary. Existing joining solutions often have restrictions due to the principle of joining. Thus in this article a new high speed forming method for the micro range is shown, which is based on plastic deformation by laser induced shockwaves. First of all it is shown how metal sheet-sheet joints can be realized with this method. With the produced joints tensile tests are carried out, where a maximum shearing force of 26.7 N could be achieved. For a detailed process understanding, the near-field of the acting pressure of the TEA-CO2-laser induced shockwaves is measured. Moreover it is determined that the ignition point of the TEA-CO2-laser induced plasma out of aluminum is about 8 mm above the surface.
