SIMUFACT.WELDING is a high performance Finite-Element-based software with state-of-the-art solver technology allowing for elastic-plastic material behavior to be modeled. As one of the most important tasks, the software succeeds in realistically predicting the distortions and residual stresses that occur during welding, while considering phase transformations and microstructure.

SIMUFACT.WELDING also assists in finding the optimal clamping devices for the welding process and helps determine the best welding sequence to minimize distortion.  Multiple welding sequence and clamping setup can be simulated in a short time.

SIMUFACT.WELDING development started in 2005 with a German research group in Welding simulation comprised of major car manufacturers BMW, AUDI, MERCEDES, PORSCHE & AUDI.  The first commercial release was in 2010.  In addition to SIMUFACT solver, WELDSIM solver from IFE is available for welding of aluminum parts.


SIMUFACT.WELDING is a powerful simulation software allowing you to study and optimize your welding process beforehand

SIMUFACT.WELDING allows to reduce the dependence on empirical data and experience for welding processes. A better Understanding of the welding process helps reduce time and effort for correction post welding

SIMUFACT.WELDING allows to test different clamping concepts, paths and weld sequence to minimize distortion and improving quality.

SIMUFACT.WELDING can also predict mechanical properties in the Heat Affected Zone (HAZ) post welding, including phase transformations.

Combining SIMUFACT.WELDING with other commercial FEA software like ABAQUS allows to analyse operational loads on structure considering the residual stresses and material properties after welding.
