One of the great advantages of laser welding of plastic is that the weld seams are very homogeneous and therefore leak-tight. The process is ideally suited for achieving IP67 or higher protection levels in a process-safe manner. Even in the…
Probably one of the most influential patents on laser welding of plastics is a patent EP 0 751 865 first filed by Marquardt GmbH in 1994. It protects the welding of two workpiece parts using the transmission method, which have…
Today, it is widely believed that laser welding of plastics was invented around the turn of the millennium. However, old patents and patent applications in particular show that the technology was considered and also used much earlier. For example, Mobil…
Radial laser welding of radially symmetrical assemblies, such as connectors and tubes, is of particular importance. Unlike the other process variants, no additional clamping force is usually applied due to the joining geometry. Nevertheless, to ensure good thermal contact and…
Advanced Quasi-Simultaneous Welding, or AQW for short, is a new, patented process. It uses the advantages of conventional laser welding and combines this with the advantages of the EvoClear process for clear-clear welding. As a result, a significant reduction in…
