Abstract
The physical-mathematical model of drop transfer phenomena in consumable electrode welding with short-circuiting of the arc gap is considered, which allows for conditions of electrode metal transfer and interaction of the arc with electric parameters of the power source. The software realizing the numerical solution of the model equations makes it possible to study the phenomena occurring in welding and justifiably determine not only the technological parameters of the process, but also the technological requirements to design of various types of consumable-electrode arc welding equipment.
