Abstract

A digital twin is the virtual representation of a physical object, system, or process using computerized digital technologies. Creating digital twins becomes much more difficult for dynamic manufacturing processes, such as welding, when simulation time should not exceed a few seconds. This paper presents a method for modeling thermal fields in industrial welding in real time, based on physical processes. The method can be used to create a digital twin at the process level. The method uses analytical solutions to the problem of temperature distribution around a weld which is a moving heat source.
