Competences
Welding distortion management with DynaWeld is the virtual testing of component or component group tolerances.
DynaWeld supports you in planning and verification your manufacturing processes for welded assemblies – in industrial series production or in complex and expensive individual components.
We can use our simulation methods to predict geometry deviations of your assemblies in advance. We identify critical areas in your manufacturing concept and help to remedy them. With our simulation, we can ensure the robustness of your production with regard to process parameters, clamping devices or influences of geometric deviations of the intermediate products.
This also includes the determination of permanent residual stresses or microstructure states from the welding process.

Gaps occurring (right) when welding aluminum profiles (left)
Detect gap formation during welding with DynaWeld welding simulation
Thermal expansions already lead to deformation of the components during welding. This can lead to components moving apart at the joining zone. The formation of this gap endangers process stability and leads to significant shape deviations. This gap formation is to be limited or prevented with a clamp device. Alternatively, tack welds are used to fix the components. With [...]
Induction hardening with DynaWeld
Induction is an efficient method for targeted heating. Components can be heated both completely and partially. Induction heating can be used for welding, straightening, preheating or for heat treatment. We have developed a modeling method to image inductive heating to a 3D model. We use the boundary element method, which means we can do without meshing the air. That [...]

Application example for a successful heat management design.
DynaWeld for heavy machinery construction – heat management during welding
Heavy machinery construction places special demands on the design of welded joints. Solid components with sheet thicknesses between 100 mm and 500 mm absorb the welding heat much faster than thin-walled components. The result is high cooling rates with common welding processes such as gas-shielded metal welding or submerged arc welding. Steels that can be welded in the thin [...]

Validation tests for the welding simulation
DynaWeld at the Technology Institute for Metal & Engineering GmbH (TIME) The prediction accuracy of numerical simulations can only be convincing if the models used are suitable for the physical processes and the modeling is realistic. A check can be done on the basis of welding tests. So far, one can find in the literature for verification purposes [...]
