Simufact Welding

Special weld structure software for virtual tests and process design for the optimisation of assemblies

Simufact Welding 은 여러 가지 용접 순서를 포함하는 복잡한 용접 프로세스를 시뮬레이션 할 수 있습니다. 또한 프로세스 중에 발생하는 위상 변환을 고려하면서 구성 요소의 왜곡을 예측합니다. Simufact Welding을 사용하면 용접 이음부의 특성 및 고온 균열과 같은 용접 결함에 대해 예측할 수 있어, 제조 공정을 결정하기 이전에 발생 가능한 문제를 해결할 수 있습니다.

Simufact Welding과 Simufact Forming을 결합해 사용하면, 업스트림 및 다운스트림 용접 프로세스와 다양한 프로세스 체인의 조합을 시뮬레이션 할 수 있습니다. 용이한 데이터 전송은 성형 이력을 고려할 뿐만 아니라 가상으로 용접된 이음부의 강도 분석도 가능합니다.

Exactly the right welding process you need

With the Arc Welding module common arc welding processes are simulated. Residual Stress, strain and distortion as caused by the welding process are predicted. This enables an improved quality and dimensional control.

Simufact Welding allows to evaluate the impact of vaious parameters, like: weld sequence, arc welding process parameters and fixturing strategy.
Multiple weld robots can be configured. Weld fillets are modelled very easily using the internal fillet generator.

Simufact Weldiing makes use of a comprehensive material database that can be extended by the user.

Laser- and Electron Beam Welding processes are simulated to predict the local distribution of residual stress, strain and distortion.

Simufact Welding takes into account the specifics of a Laser or Electron Beam heat source. This complements the extensive capabilities that are offered for simulating arc welding processes and enables an accurate prediction of any physical Laser and Beam welding process.

With Simufact Welding, Resistance Spot Welding processes are simulated with a high accuracy. The impact of multiple parameters like spot sequence, welding process parameters (force, current, time) and fixturing/clamping strategy on the weld structure is predicted.

The flexible configuration of the simulation in different modes (thermomechanical, mechanical with electrode movement and simplified) enables a fast simulation for complex assemblies.

Simufact Welding enables the quick and efficient setup  of robust laser metal deposition (DED) models in order to calculate and evaluate for stress, strain, distortion, thermal history, and hot spots during manufacturing and post processing.

Common robot programming such as the G-Code can be utilized - This allows users to simply import existing tool paths instead of defining weld paths manually.

Brazing is a thermal process that applies hot soldering material to join parts. The Simufact Welding Brazing module takes care of the specifics of this process: the heat input for example is limited to the soldering material only - the soldering material itself is modelled by fillets.

Brazing simulations can be defined using both conventional and beam heat sources, or a combination of them.

Virtual Clamping enables to predict the exact geometry for parts and assembled structures. Simufact Welding simulates the behavior of parts as they are clamped and welded in their designated (for example: vehicle) coordinates - This dramatically reduces the need for prototypes or tryouts.

Stress relieving reduces residual stresses in the assembly after welding. Usually the application of this heat treatment method involves controlled heating of the assembly, a certain holding period at elevated  temperature as well as controlled cooling - The simulation enables virtual tryout to achieve the best possible heat treatment process

Your benefits with Simufact Welding


Design and optimise your welding process:

  • Determine the optimal weld sequence and parameters, as well as clamping and unclamping concepts, to minimise thermal distortions and residual stresses and ensure a robust welding process.
  • Identify and eliminate potential welding defects, such as hot cracks.
  • Investigate material behavior during welding, such as phase transformation.

Simplicity – No CAE expert knowledge required as the software solution is designed to be user-friendly, intuitive and process-oriented.


Sustainability – Save material, time and money by replacing expensive and time-consuming physical tests with virtual tests.
