The paper presents data on formation of pores in metal during surfacing by manual and mechanized open arc welding with the BrKMts3-1 grade wire. Dependence of preheating of parts on the quantity of pores in weld metal is determined. It is established that formation of pores in welding of copper and its alloys is connected with hydrogen and oxygen. Equilibrium concentrations of oxygen and hydrogen in liquid metal (bronze) at temperature Т = 1473 K are defined.
