提出了电弧柱-阳极区-蒸发阳极系统中电磁过程的数学模型.具有蒸发金属阳极的电弧的阳极区域由一个模型描述，在该模型下，包含蒸发金属的原子和离子的非平衡近阳极等离子体，沿着环境（惰性）气体的原子和离子，被细分为紧邻阳极表面的空间电荷层和邻近电弧柱的电离区域。该模型允许根据阳极附近的电流密度和等离子体温度以及其表面的温度来确定焊接电弧柱等离子体和阳极表面之间的电位降。
A mathmatical model of electromagnetic processes occurring in the ‘arc column – anode region – evaporating anode’ system is presented. The anode region of electric arc with an evaporating metallic anode is described by a model, under which the non-equilibrium near anode plasma containing atoms and ions of the evaporated metal, along with atoms and ions of the ambient (inert) gas, is subdivided into a space charge layer immediately adjoining the anode surface and ionisation region adjacent to the arc column. This model allows determining the potential drop between welding arc column plasma and anode surface depending on the current density and plasma temperature near the anode, as well as upon the temperature of its surface.
