In this communication, a electron beam welding process is studied. The work focused on the identification of the power density and the position of a gaussian heat source. The Levenberg-Marquardt method is employed to solve the inverse heat source problem. The welded material is cut in several planes and the identification is performed for each planes. The, a pseudo 3D heat source is reconstructed from these results.
