基于电弧物理理论，建立了单缆式气体保护金属极电弧焊（GMAW）电弧的三维数值模型。研究了不同保护气体流量对温度场、速度场和压力场特征的影响。结果表明，随着保护气体流量的增加，电弧等离子体沿径向的最大速度和工件表面的电弧压力明显增加，而电弧温度变化不大。这种现象主要归因于电弧等离子体之间的碰撞增多以及缆式七线的自转作用。电缆型导线尖端处的电弧温度达到最大值。电弧等离子体的最大流速位于焊丝尖端（1-9mm）。中心轴上的所有电弧压力均达到最大值。仿真结果与实验结果一致。
A three-dimensional numerical model of arc in gas metal arc welding (GMAW) with single cable-typed wire was established based on the theory of arc physics. The influences of different shielding gas flow rates on the features of temperature field, velocity field and pressure field were investigated. The results showed that the maximum velocity of arc plasma along radial direction and the arc pressure on the surface of workpieces were increased obviously with the shielding gas flow rate increasing, while the arc temperature was changed little. This phenomenon was mainly attributed to the increasing collisions between arc plasmas and the self-rotation action of cable-typed seven wires. The arc temperature at the tip of the cable-typed wire reached the maximum. The maximum flow velocity of arc plasma was located at the tip of wire (1-9 mm). All the arc pressure in the central axis were reached up to the maximum. The simulation results were in agreement with the experimental results.
