Simufact Welding

Simufact Welding

Special weld structure software for process design and optimization of assemblies.


Simulation of fusion & pressure welding, and directed energy deposition (DED) AM process

One single pre- and post-processing environment specifically for welding processes

Open architecture for easy and seamless results import & export through UNV data format

Powered by MARC, the world's leading non-linear solver

First-class solution for fusion and pressure welding processes

Simufact Welding is used for modelling and optimizing a wide range of fusion and pressure welding processes, taking into account 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 modelled in Simufact Welding. Additionally, 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.

The key benefits of using Simufact Welding include:

Comprehensive software solution for welding processes

Calculate the precise effects of processes such as arc welding, laser and electron beam welding, resistance spot welding, and brazing. Simufact Welding even has the capacity to model the effects of ‘Direct Energy Deposition’ used in the manufacturing process for optimal printing results.

Features of Simufact Welding include:


Design and optimisation

Determine the optimal weld sequence and parameters, as well as clamping and unclamping concepts, to minimize thermal distortions and residual stresses and ensure a robust welding process and identify and eliminate potential welding defects, such as hot cracks.



Our software is designed to be user-friendly, intuitive and process-oriented, so that the use of our software in your company is possible in a very short time without expert knowledge.


Seamless result transfer

The results between Hexagon's software solutions can be transferred into each other to cover the entire process/manufacturing chain and achieve the most accurate end result possible.



Save time, material, and money, by eliminating expensive physical try-outs and conducting every test in an accurate and realistic virtual environment.
