Welding & Assembly

ESI SYSWELD is an easy-to-use and robust software package to simulate all the multi-physics involved in Welding, Assembly and Heat Treatment manufacturing processes. From weld quality to body manufacturing & distortion engineering, SYSWELD offers a unique computer-aided assessment of material characteristics, residual stresses and distortions of a welded structure.  Welding & Assembly simulation minimizes the cost of manufacturing planning, try-out and fabrication validation and time to market. This allows our customers to spend the majority of their time creating new, innovative products. 

Highlights of ESI SYSWELD 2019 

Productivity

  • Manage distortions of the complete global assembly based on different pre-computed subassemblies with mapping on deformed geometry, mapping with initialization of physical properties, mapping with geometrical transformation etc.
  • Significant improvement in the robustness and performance with new contact formulation (Nistche method)
  • Ensure weld quality by accurate prediction of the final grain structures of the welded joints
  • Predict part distortions for Heat treatment – machining (material removal) chaining. Update machining sequence to ensure the geometrical tolerances 

Simplicity

  • Thanks to improvements in DMP facilities, restart of the computation can be handled easily and at any time of the computation  
  • For multi-pass welding, automatic definition of the inter pass temperature is now also available in the batch mode
  • For heat source calibration, user can now superimpose welding simulation temperature results with the experimental macrograph

Convenience 

  • Heat power display has been developed in visual weld to have a direct look of heat power distribution that will be transferred to the component during simulation.  
  • For welding-assembly chaining scenarios for specific alloys where phase transformation can occur, developments are done to support the mechanical properties dependency versus the phase proportions.
