Abstract
The mathematical modeling of real welding technologies based on a physicochemical analysis of the interaction between the phases (metal, slag, and gas) is employed in the present work. The model is based on the fundamental equations of thermodynamics and kinetics of high-temperature metallurgical reactions and factors which take into account the thermal and hydrodynamics conditions of the real process. Such an approach permits optimization of the composition of the materials and the technology of the process already in the planning stage with minimal expenditures of time and materials. The model is used to develop fundamentally new compositions for electrode coatings and flux-cored electrodes (including those based on the use of industrial waste products and recycled materials). The performance and adequacy of the model was tested using special technological experiments and as the research goes on the software is modified. The data base of the model includes the relevant experimental and theoretical data concerning the complex interaction of various alloying components.
