Abstract
Some approach to increase the mechanical properties of welding joints, for example strength, has been considered. It has been proposed to increase the mechanical properties by limiting on zone of high temperature heating by the use of hard dioxide carbon as a coolant. It has been accomplished the numerical simulation of arc welding of welding joints to calculate the temperature field of pieces. It has been used non-symmetric three-dimensional model of the heat source. The model had the heat flow distribution in double ellipsoid area as the Gaussian law. Numerical simulation demonstrates the decrement of zone of high temperature heating in the course of arc welding with the use of hard dioxide carbon as a coolant. Strength of welding joints of austenitic steels under different cooling conditions has been defined. It is found that the use of hard dioxide carbon had led to increasing of strength e in comparison with the strength of welding joints accomplished under usual conditions.
