We consider electric arc, electroslag welding with a consumable electrode, as well as other types of welding (gas, plasma, etc.) using rod filler materials. Two schemes of the corresponding type of welding are distinguished - the first, when an electrode has a finite length, the location of the current lead relative to it is stationary. In the second case, the electrode moves relative to the place of current supply in such a way that the length of the part of the electrode from its end to the place of current supply during welding varies little. A number of assumptions are made, a mathematical description of the heating and melting of the electrodes, filler materials due to the heat of the welding sources, and ohmic resistance is presented. Relations are given for estimating the temperature distribution along the length of an electrode, filler rods, and their melting rate.

我们考虑电弧焊，使用易耗电极的电渣焊，以及使用焊条填充材料的其他类型的焊接（气体，等离子等）。区分了两种对应焊接类型的方案-第一种方案是，当电极的长度有限时，电流引线相对于其的位置是固定的。在第二种情况下，电极相对于电流供应位置移动，使得在焊接期间电极的一部分从其端部到电流供应位置的长度变化很小。进行了许多假设，给出了电极加热和熔化，由于焊接源的热量引起的填充材料以及欧姆电阻的数学描述。给出了用于估计沿电极长度的温度分布的关系，
