"This paper deals with new approach of measurement of the concentration profiles, concerning the redistribution of substitution elements in close vicinity of welded joint of two different steels. These concentrations have been measured in three straight lines in a plane perpendicular to the weld interface. The concentration profiles have been evaluated from experimental data by modelling of diffusion based on 2nd Ficks law. Original computation program for nonlinear regression was evolved based on Levenberg - Marquards algorithm for evaluation of diffusivities and other quantities." .
