Summary
The knowledge of the temperature distribution of the workpiece during arc welding is necessary in order to ascertain changes in the material structure as well as the strength of the joint. The simulation has not only to consider the heat effect of the arc but also the weld pool deformation influenced by arc pressure and gravitation. A coupled nonlinear system based on the description of energy transport and minimization of surface energy has been employed. The system is solved using a stabilized finite element method of Galerkin/least-squares type. Numerical results for examples are given. Furthermore we discuss the robustness of the numerical method.
