Simulate reality – deliver certainty through the virtual weld and 3D-metal printer

Welding is defined as a “permanent connection of components through application of heat and/or pressure”. The components are connected either by melting or by heating, and by applying additional forces (pressure). There is no other joining process which allows such resilient and dense connection with minimal space requirements. Furthermore, welding is the method of choice when it comes to the joining of assemblies with high levels of complexity. Although joining is the main application field of welding processes, it is also used in deposition processes in order to create durable and hard surfaces by means of cladding. With Additive Manufacturing, a new kind of welding is established to create components from powder material.
With the beginning of the computer age in the 1970s and 1980s, the numerical prediction of manufacturing processes using FEM was gradually getting better and has established itself in the industry since the 1990s as a standard tool. Unlike in metal casting and forming industry, however, the everyday use of FEM-simulation tools for welding and additive manufacturing processes is now just emerging. This paper will give a short classification of welding simulation types and a structured overview on the technical questions. Selected case studies and the benefits achieved through simulations with the software Simufact Welding and Simufact Additive are discussed. Finally an outlook on future developments will be given.
