The paper proposes a numerical method for analyzing the complex phenomena’s that appear in the case of keyholes welded pool geometry. Present model consist in a succession of analyses steps, needed to solve the interaction between the liquid/solid, liquid/protection gaze and liquid/MHD welded arc for arc welding, or electrons, or electromagnetic waves. The liquid/solid geometry result by dissipation of the welding power source in a matrix of many point sources. This process gives a first approximation of temperature fields and a good approximation of the digit 3D position, and information about the vaporization area.
