Simulation of the Temperature Profile During Welding with COMSOL Multiphysics® Software Using Rosenthal's Approach
发布日期 2014
A 3D finite element analysis is carried out, using COMSOL® software, to reproduce the thermal profile obtained with Rosenthal’s equation. The implemented heat transfer equation has been modified as a means to approximate Rosenthal’s solution. An analysis of the differences between the simulation and Rosenthal’s solution, when the geometry of the domain and the source are changed, has been performed. In addition, the significance of temperature dependent thermal coefficients k and Cp has been studied. A way to model the temperature profile based on Rosenthal’s approach is proposed, as well as a strategy to model the thermal profile during tandem arc welding.
