The objective of the work was development of a calculation model for practical prediction of the kinetics of formation of multicomponent endogenous nonmetallic inclusions in the weld metal. The proposed mathematical model is a nonstandard nonlinear boundary problem for a system of diffusion equations with the specific condition on the moving melt-inclusion interphase, and it allows for the kinetics and heterogeneity of the process under the conditions of the real thermal cycle of welding. The calculation program developed as a computer realization of the constructed model allows evaluating in a computer experiment the size and composition of endogenous nonmetallic oxide inclusions, depending on concentration and thermal conditions in the weld pool. 10 Ref., 2 Figures.
