Modeling of Heat Source Based on Parameters of Electron Beam Welding Process

In the paper thermo-mechanical analysis of Inconel 706 tube welding process was presented. Tubes were joined using electron beam welding EBW. Process simulation was performed using finite element method, FEM Key aspect of welding process simulation is definition of heat source. Geometry of heat source and heat input have direct impact on fusion zone, FZ, and heat affected zone, HAZ. The goal of the work was to design EBW that will produce FZ of required depth. The set of process parameters was identified based on work of Ferro for Inconel 706. Modification of the process parameters was required. For this purpose partial least square method, PLS, was used. PLS model was built using results of own work on EBW for 18-8 steel. The model was applied to Inconel data. The results calculated by PLS model were used to build FEM model.
