Abstract
- Numerical modeling of thermal processes in weld pool formation in low-alloyed steel under the impact of the electric arc was performed. Different arcing modes are considered. A qualitative difference in propagation and dissipation of thermal energy is found, depending on the modes. Mechanisms of self-organization of thermal structures were studied, which are due to highly non-linear thermophysical properties of low-alloyed steel, modes of thermal energy feeding into the weld pool and features of its dissipation on the boundaries. The validity of the numerical model is confirmed experimentally, that allows recommending the results of computer studies for practical application. [ABSTRACT FROM AUTHOR]
