Object of research - the reaction zone in arc welding and surfacing, welding fluxes and welding. Purpose - Development of theoretical physico-chemical model of interfacial interaction of melt slag, metal and gas phase. Definition of principles that combine superior welding technological properties of the flux and the possibility of controlled steel slag ability to influence the weld metal. Set features impact manufacturing techniques and structure of grain quality characteristics of flux on the weld metal. Research methods - computational and experimental. Calculation methods determined by the composition of gas phase processes on the interphase surface reaction zone of the welding flux and thermodynamic analysis of reactions performed on interphase surfaces of the reaction zone of welding. Experimental methods studied the physical features of the existence of the reaction zone of welding, fabrication of research parties fluxes and study their metallurgical and physical properties Determined the necessity of considering the provisions of nonequilibrium thermodynamics in the calculations of metallurgical processes. Studied chemical processes in the smelting flux. Certain principles of welding fluxes with improved safety and environmental indicators developed technological conditions of production of processed and ceramic fluxes. SUBMERGED ARC WELDING, GAS PHASE OXYGEN, INTERFACES, THERMODYNAMICS, PHYSICAL PROPERTIES OF THE SLAG, TECHNOLOGICAL PROPERTIES OF PELLETS, THERMAL DISSOCIATION.
