Simulation for welding applications

Welding engineers seek to understand thermo-mechanical phenomena occurring during welding processes.
Thanks to simulation, they can obtain this information upstream of the production phase, allowing them to optimize their welding operations and choose the appropriate materials.


What are your issues? How can simulation help you?


Anticipating critical welding defaults

To ensure the welded assembly conformity by highlighting the residual stresses of the various elements, but also to observe the deformation due to the welding of the assembled objects.


Understanding metallurgical behaviors

At macroscopic level, to observe the metal behavior during phase changes and to study the metallurgy of the solid at the bonded interfaces.


Optimizing the assembly

To define your welding process parameters and choose the best compromise in order to combine quality and savings.

Study all types of welding

TRANSWELD laser welding meshingSimulation is a competitiveness lever. It allows you to study welding processes quickly and without great expenses.

Whether you are a process specialist with or without filler material, you can observe the behavior of your welded assembly using a simulation software such as TRANSWELD® and then, through the prototyping, validate the best results obtained with simulation.
Through scientific models implemented in simulation software, modeling makes it possible to anticipate the shape of the welding burr for processes such as friction or electrical welding, and also for the deposition and shape of the weld bead for arc or laser welding.

In order to avoid risks of rupture of your assemblies, simulation makes it possible to highlight defects such as unfilling or excess, hot or cold cracks but it also allows you to follow the evolution of the impact of the weld on the joined elements and thus, anticipate the risks of assembly rupture. All these features ensure that you are line with established compliance and offer secure assemblies.

Care about the metallurgy of the solid

TRANSWELD Rotary Friction WeldingThanks to simulation, you can also deeply explore the material by studying solid metallurgy.

With the implementation of the CAFE resolution method (Cellular Automata Finite Element), the simulation allows you to precisely calculate the grain distribution but also to observe the nucleation and growth phases up to grain orientation, and this, during the solidification phase.

For steels alloys (carbon alloys and low-alloy steels), you can automatically generate TTT diagrams (time-temperature-transformation) calculating the phase transformation curves from the chemical composition or from a TRC diagram.

Through a rich database offered by JMatPro® and available in our solutions, analyze precisely the mechanical properties (hardness, residual stress, etc.) linked to phase changes and geometric variations (distortions) in order to produce high-quality parts.
