Abstract
Development of complex calculation algorithm based on system approach for numerical prediction of formation and growth of non-metallic inclusions in a weld metal is one of the important tasks in present time. One of significant blocks of it is a calculation estimation of weld metal chemical composition in arc methods of welding, which is of interest and being studied in present work. A procedure was proposed for calculation of content of weld pool melt in arc welding. The developed procedure is based on modelling of thermodynamics of interface interaction in metal–slag–gas-vapor phase system in a temperature range typical for weld pool existence in arc methods of welding. Predicted content of metal melt can be a basis for modelling of content, size, morphology and chemical composition of non-metallic inclusions in weld metal. 11 Ref., 3 Tables, 3 Figures.
