Among industrial technologies, carbon dioxide welding occupies a leading position. However, this welding method is characterized by increased spattering of metal and splashing it on the welded piece of work. A protective coating layer applied to metal is effective means of preventing the consequences of this disadvantage. The paper developed the method for determining the minimum allowable thickness of the coating, sufficient to prevent the interaction of molten metal drops with the surface of the welded pieces of work.
