    Goldak Technologies and DynaWeld starts partnership
    John Goldak mets Jens Rohbrecht and Tobias Loose at Seggau conference this autum. We discussed our visions on welding and heat treatment simulation software - suitable for industrial application and use.
    Goldak Technologies Inc. and DynaWeld decided to start a partnership.
    DynaWeld is now distributor of Goldak´s software VrSuite

    Goldak-VrSuite is an entire software environment for welding, heat treatment casting and fracture mechanics. It covers process simulation, structure simulation, microstructure analysis on macro and microscale as well as optimisation with high efficient solution algorithms and maximum level of automatisation. As John Goldak says: "it is a designer driven software" - tailored for the operator who wants to design his manufacturing process.

    New Sorpas interface for DynaWeld
    DynaWeld and Swantec aggree to develop an interface between Sorpas2D and DynaWeld. The new interface enables the user to export process simulation results from Sorpas and continue the simulation with DynaWeld. It benefits the DynaWeld user with the integration of high elaborated and well benchmarked resistance spot weld simulation from Sorpas.

    Sales partnership with UIT SOLUTIONS in South Korea
    In September, UIT SOLUTIONS from Seoul in South Korea, represented by Seve Kim, Managing Director at UIT, and Mark Kim visited DynaWeld in Wössingen. At the meeting it was discussed how the products and services of DynaWeld can be provided for the Korean market. UIT and DynaWeld agree on a sales partnership. UIT henceforth will distribute DynaWeld in Korea.
    COMTES DFM becomes sales partner for the Czech Republic and Slovakia

    COMTES DFM from Dobřany in the Czech Republic becomes distributor for DynaWeld in the Czech Republic and Slovakia. Preparatory discussions on future collaboration have already been carried out at the JMatPro user conference in Wuppertal in June this year. COMTES is primarily concerned with the heat treatment, hot forming, materials science and the determination of material properties. Already during the development phase of MatPlusHQ, Jens Prehm (DynaWeld Kamen) was in close contact with Pavel Šuchmann from Comtes.
23. - 27.09.2018
    DynaWeld attends the 12th seminar on numerical modeling of weld phenomena in Seggau, austria. At the international conference, researchers and users of the welding simulation come together and report about recent research results.

    KIT Karlsruhe uses DynaWeld for research projects
    Dipl.-Ing. Andreas Metzger, Research Centre for Steel, Timber and Masonry, KIT Karlsruhe, is investigating a process in which sheets are welded together and then inflated under pressure: Die-Less-Hydroforming. Metzger uses DynaWeld to numerically investigate the coupled process. Metzger presented latest results at this year´s LS-DYNA conference in Detroit. The publication can be downloaded directly from the website with the following link:
    9th day of welding practice in Rostock
    At the SLV Mecklenburg-Vorpommen DynaWeld presented possible applications and saving potentials of welding simulations. Of particular interest was the multi-layer simulation, which provides information about the microstructure and material conditions after welding. ZTU data for the calculation is provided by the Weldware® program developed in Rostock.
    DynaWeld Release June 2018
    New functionalities in DynaWeld:
    • Tied shell edge to solid contact applicable on MPP

    JMatPro user conference in Wuppertal
    DynaWeld participated in the JMatPro user conference in Wuppertal, which was organised by Matplus GmbH. The coupling of the material simulation with the heat treatment simulation or welding simulation enables the controlled component design in the drafting stage. DynaWeld has presented the possibilities and advantages of this simulation method in Wuppertal. Both MatPlusHQ and DynaWeld® have corresponding interfaces to JMatPro to realize the coupled simulation.
