One-dimensional models of electric welding arch
The article deals with the basic models of electric welding arch, their principal characteristics as well as advantages and disadvantages. It demonstrates that the known models of the arch do not permit to reveal the physical processes taking place when welding by fusion nor the rise of vorticity magnetic field is taken into consideration. When taken, another concept of physical processes in the arch ensues. The article contains the basic principles of the vortical electrodynamic model which gives a better idea of the real physical processes occurring in the arch.
