Abstract: This article presents the results of research on the peculiarities of the weld bead geometry of stainless steel CrNi18-10 during of pulsed metal inert gas welding (A-MIG) and the influence of the thermodynamic and physicochemical properties of oxides used as fluxes in gas-powder mixtures used for pulsed A-MIG welding. The obtained research results allowed to determine the influence of thermodynamic and physico-chemical properties of individual oxides used in gas-powder mixtures on the quality of weld bead geometry and to identify recommendations for the selection of oxide compounds for pulsed A-MIG welding of stainless steels that would provide quality formation of weld beads.

Keywords: physical and mechanical properties of chemical compounds, gas-powder mixture, feeder, pulsed metal inert gases welding.
