Abstract

The modelling of welding processes has recently become one of the most important tools to support the experimental research and the production implementation of welding processes. The literature is very rich in publications containing elements of single source modelling of welding processes, but the growing industrial interest in the use of hybrid welding sources creates a new field for the study of these processes using numerical simulations. In the present study, an attempt has been made to create a conventional and hybrid heat source in a software dedicated to performing numerical simulations using the FEA method - LUSAS FEA 14.7. As a result of the study, based on studies of the temperature field and thermal cycle of welding, it was possible to verify the classical Goldak model. Furthermore, the study showed that the proposed hybrid heat source model fairly well reflects the temperature distribution changes in hybrid welding.
