Wire arc welding-based additive manufacturing (WAAM) is a 3D printing technology for production of near-net-shape parts with complex geometry, where in comparison to conventional production technologies the efficiency of used material is significantly improved. Because the process itself involves thermo-mechanically complex physical phenomena, finite element-based virtual models are commonly employed to optimize the process parameters. This master's thesis presents advanced computational modelling of the WAAM process, based on the SIMULIA Abaqus software environment. By simulating and manufacturing a geometrically simple product, the results of the computer simulation are also experimentally assessed.
