  • Dynamic beam shaping increases the attractiveness of laser beam fusion cutting

    Press release (Nr. XV) - Fraunhofer IWS / 21.10.2016

    The decisive argument for purchasing a laser cutting machine is the optimal combination of good quality, maximum feed rate, low investment and operating costs. During the last years, fiber and disc lasers have achieved a leading position as a laser source for cutting of thin metal sheets due to their distinctly higher cutting rates. The need for optimization emerges for sheet thicknesses exceeding 5 mm. Compared to CO2-lasers, the solid state lasers cause an increase in surface roughness and burr formation.

    Last night, Fraunhofer IWS Dresden received the second prize of the EARTO Innovation Awards 2016 in the category Impact Delivered for the: Development of super hard diamond-like carbon coatings for improved energy efficiency. These coatings are applied on piston rings and other parts in the powertrain. Coated piston rings show a reduction in fuel consumption of about 1.5 % or 3 g/km CO2 emission. Series production has started. Further components will follow.

    Joining of completely novel material combinations, new construction principles, and production processes guaranteeing high quality – these are the challenges to which enterprises and the scientists at Fraunhofer IWS have been standing up for years. Parts and assemblies are expected to be possibly light, strong, durable and reliable. The application of hybrid joints between metals and reinforced composites in the automotive, aerospace and many other areas are a new trend, which is significantly swayed by Fraunhofer IWS Dresden, and is presented at EuroBLECH 2016.

    Material savings, flexible production and high user comfort are increasingly gaining importance in the field of railway vehicles. Analyses and simulations of passenger flows in vehicle interiors allow for an improved vehicle body layout. Mass-reduced manufacturing of sidewalls with individualized door-cuts can be optimized by low-distortion laser welding and completely connected integral structures. At the trade fair InnoTrans 2016 the Dresden Fraunhofer institutes IWS and IVI are presenting jointly developed technical implementations for passenger flow simulations and manufacturing techniques for low heat input and highly efficient laser welding procedures.

    Together with Technische Universität Dresden the Fraunhofer Institute IWS Dresden runs the Center for Additive Manufacturing Dresden. This internationally attention-attracting institution is the biggest center of competence in Eastern Germany for the development of high-tech parts via 3D-printing. From here, AGENT-3D, the biggest in Europe research program in the field of additive manufacturing, is being managed as well. Currently, allowances from the project executing organization Forschungszentrum Jülich GmbH worth of 5.3 Million Euro are available for the Fraunhofer Institute IWS for strategic, management and technology projects. Numerous enterprises take part in the program as well.

    From 31. May to 2. June Fraunhofer IWS Dresden will present at the International trade fair for laser material processing LASYS in Stuttgart innovative technologies and systems capable for integration into industrial production processes. An emphasis is layed on the long-standing systems COAXn und COAXwire for powder and wire deposaition welding. For the first time the recent development COAXwire2016, which is operational also in combination with a diode laser, will be presented. This development is convenient for the processing of flux cored wire and thus offers an even broader spectrum of applications as its forerunner.
