摘　　要：The electrical conductivity is indispensable for the underwater wet welding arc simulation. In order to get this parameter, the composition of the underwater arc is analyzed, and the electron content is obtained. Then the current formation mechanism in the arc and the effective collision cross-sectional area between the electron and ions is discussed. The calculation methods and results analysis are presented in this paper.The electrical conductivity is indispensable for the underwater wet welding arc simulation.
