A new welding head – remoweld®FLEX – for high frequency laser material processing of difficult to weld materials

Due to digitalized product development and cross-linked manufacturing cycles development periods have been radically shortened. Rapid product change requires from manufacturers and suppliers a high rate of flexibility, so that customized and cost-optimized solutions can be offered. For the development of new laser welding technologies individualized processes tailored for specific materials and products need to be combined with innovative hardware concepts. For the welding of difficult to weld materials a new high frequency beam oscillation welding head with integrated process monitoring – the remoweld®FLEX – has been developed, which is going to be presented at the industrial trade fair LASER World of PHOTONICS in Munich.

µRevolution – worldwide most compact system for surface structuring by means of scanner-based direct laser interference patterning

Functionalization of technical surfaces by means of natural, bio-inspired structures is an innovation driver of the 21th century. The functionalities achieved are applicable for e.g. improved bio-compatibility in medical and biotechnological industries, for tribological applications in the automotive industry and for optical applications such as product and brand protection. Fraunhofer IWS has been developing modularly designed solutions for surface functionalization tasks by fabricating micrometer and sub-micrometer structures in a targeted and flexible manner. Scientists of the Fraunhofer IWS will present for the very first time the worldwide most compact system for surface structuring by means of scanner-based direct laser interference patterning at the tradeshow Laser World of Photonics in Munich.

New IWS laser welding technology received certifica-tion by DNV GL - Maritim for welding processes in the shipbuilding industry.

Confidence and reliability are key criteria for the potential introduction of innovative joining techniques. This is, in particular, also true for the modern maritime industry. Scientists of the Fraunhofer IWS have developed a novel, low heat-input but highly efficient laser welding technology for joining processes of up to 50 mm thick parts made of seawater-resistant aluminum alloys. A decisive advantage of this technology is the comparatively low laser power (< 4 kW) needed during the welding of thick metal sheets. The low laser power enables extraordinarily small weld seam widths and minimal component distortion. The IWS laser multi-pass-narrow-gap welding technology (laser MPNG) has been successfully certificated by the classification society DNV GL and is thus now ready for potential industrial applications.

Professor Martina Zimmermann has been elected to be the new speaker of the German Materials Society (DGM) advisory board.

Prof. Dr. Martina Zimmermann, head of the Fraunhofer IWS expert team “Materials Characterization and Testing” and holder of the professorship for “Mechanics of Materials and Damage Analysis”, TU Dresden, has been elected to be the new speaker of the German Materials Society (DGM) advisory board. The election took place within the framework of the first constituent meeting of the new advisory board at the Helmholtz-Zentrum Berlin für Materialien und Energie on March 16, 2017.
