Simufact Welding is used to model and optimizing a wide range of thermal joining processes by means of the welding structure simulation under consideration of weld sequence and clamping. Processes such as arc welding, laser beam welding, electron beam welding, brazing, resistance spot welding as well as the generative manufacturing process ‘Direct Energy Deposition’ (DED or WAAM) can be modeled in Simufact Welding. Simufact Welding can be used to model the heat treatment, different variants for cooling and unclamping as well as the mechanical load on welded structures.

Release Highlights

The 5 top new features in Simufact Welding 2021 are:

  • Extension of Python API enables for smart simulation and maximized automation:
    The extended Python API scripting allows the user to easily create and calculate models from scratch, and enables data input and output to be fully automated. For example, Simufact Welding 2021 allows the user to automate model creation, such as the import and the positioning of his parts, the creation and the assignment of objects necessary to the process and their process definition. In addition, Simufact Welding 2021 now automatically initiatespost-processing such as the creation of measuring points wherever needed, and exporting or copying results into subsequent processes. Once the results has been exported from Simufact Welding 2021, the can analyse results without any limits using Python programming language.

  • New weld bead creation tool provides complete control over any shape of weld beads:
    Until now, modelling certain welds such as butt welds would require additional software. Simufact Welding 2021 has integrated a new weld bead creation tool, that serves for a complete control over any shape of your weld beads. Whether you need to simulate square butt welds, V-butt welds or T-joints with a gap: the new weld bead creation helps you to easily, quickly and intuitively create them within one welding simulation software.

  • Enhancement of DED module:
    We have improved our direct energy deposition (DED) module so that users can easily create a geometry based on the trajectories after the G-Code import. Afterwards he generates the mesh for his simulation. This entire process can run in Simufact Welding 2021. Further enhancements improved the stability, robustness, and ease of use in both model generation and simulation of DED processes.


  • New cost estimation module provides at-a-glance breakdown of entire manufacturing cost:
    Simufact has enhanced its range of applications by including a basic cost estimation module as technical preview. Users can now estimate the costs of each process in advance and optimize them prior to production. The new cost estimation module makes it possible to estimate itemized and total costs of each variant. This allows the user to compare different welding processes in terms of cost. The holistic calculaton engine considers fixed costs such as maintenance and labour costs and variable costs such as material and tooling consumables and the cost of energy used.

  • Enhancement of heat source definition based on measurements:
    Defining the heat source is essential for a welding simulation. Simufact Welding 2021 simplifies the heat source definition so users can focus on their process setup. Look forward to two major updates to the heat source definition.

  1. The Goldak’s heat source geometry and power can be estimated by using the geometric parameters of a weld bead dimensions from a weld plan or a cross-section from experiment.
  2. In addition to the conventional heat source definition by specifying the speed, power and efficiency, users can now easily specify the target temperature, the temperature tolerance aswell as the maximum current and the maximum voltage.

Use our new, quick and easy heat source definition tool to estimate the heat source dimensions and properties without spending much time and efforts for calibrating it in order to run a first-shot welding simulation.

Apart from these improvements, we have also improved/modernized the product icons, the splash screen, and the product window within the software:
