The data of the effect of the chemical composition, enthalpy, and viscosity of the molten metal in submerged arc surfacing with a strip electrode on the shape and size of the fusion zone of the parent metal has been presented. The enthalpy and viscosity of the molten weld pool depend on its temperature and influence on the liquid metal flow and heat transfer. The average values of enthalpy and viscosity of the molten weld pool of mild carbon steel and stainless steel are different. It is shown that the difference in the values of the maximum and average mass temperature of molten weld pool of mild carbon steel is much greater than that of the stainless steel molten weld pool. It should be taken into consideration that the difference in these values in some parts of the weld pool is even greater. Because of that, the effective values of enthalpy may be much higher and the viscosity much lower than the mean values. The increased fluidity of the mild carbon steel weld pool favours the flow rate and intensifies its convection. It results in asymmetry of the fusion zone cross section in hardfacing with a strip electrode on the plate with a transverse slopeReferences
