Simufact.welding: Professional welding simulation Industrial welding processes require a high degree of process security. The correct design of a welding procedure sheet is essential for the quality of a process, which is needed for the programming of welding robots among others. The correct application of clamping devices, the employed welding process and the energy input are added. Distortions of the final geometry must be fully controlled so that components can be serially produced with precise tolerances. Knowledge about the kind of the heat influence zone enables specialists to conclude the properties of welding seams. Fields of application field for welding simulation with Simufact.welding Simufact.welding is a Finite Element-based software for welding simulation. Finite Element calculations are suitable for modeling the elastic-plastic material behavior and, thus, also for simulating welding structure. Latest solver technology and a user-friendly overall concept allow to calculate welding sequences efficiently and to predict distortions of the component realistically, also with regard to microstructural changes. Simufact.welding is a particularly 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 controlling these in the component. Simufact.welding considers microstructural properties in the heat-affected zone; its form allows conclusions about the properties of the weld seam, in particular its strength. The user gains valuable clues to identify welding defects such as hot cracks in the simulation to avoid them in practice. The software assists in finding the optimal clamping devices for the welding process and delivers facts to determine the best welding sequence. Simufact.welding predicts the final contour of the component and helps to produce parts in series with precise tolerance.
