Subject aims expressed by acquired skills and competences

The graduate will acquire the knowledge, skills and competences in the field of computational methods in the fields of welding and their use. The aim of the study is to obtain knowledge of numerical methods in welding in the areas of: -calculations preheating in welding -calculations on the vulnerability in the cracks and after welding -calculations when you define each area of the weld and their structural phases -calculations using finite element methods (FEM) for the monitoring of temperature fields in the fields of welded joints -calculations using finite element methods (FEM) for the determination of deflection and stress in welding in building construction The second group is the management of the application of computing methods of welding sources, in particular in the areas of pulse, synergy and inverter resources. A third group of application of computing methods in welding is a continuous record of data in the process of welding, their subsequent evaluation and processing.
