Beschreibung

So far, laser processes for the defined weakening of metals have been investigated only in wall thickness ranges of a few millimeters. In the case considered, the sheaths of UXOs (4–25mm) are to be weakened in order to reduce danger. The developed model for the melt-ablation process with a 2kW solid-state laser enables the defined weakening of steel sheets of up to 15mm. It is ensured that a critical temperature of 300°C on the underside of the material is not exceeded. In accordance with the process requirements, a cost-effective 3D-printed disposable process head is manufactured and verified with regard to the developed model
