TY - JOUR A1 - Schkutow, Andreas A1 - Scholle, Karsten A1 - Fuhrberg, Peter A1 - Frick, Thomas T1 - Scanning techniques for optimized damage tolerance in quasi-simultaneous laser transmission welding of plastics JF - Procedia CIRP N2 - Fiber lasers are increasingly replacing the commonly used diode lasers in laser transmission welding of plastics for challenging applications due to their superior beam quality and the ability to use long working distances and small spot sizes. At the same time, these smaller spot sizes increase the risk of thermal degradation. In this work, we investigate different scanning strategies that allow controlling the weld seam widths. These strategies are characterized regarding the demands on the performance of the scanner system, the risk of thermal degradation and the mechanical properties of the resulting welds.
