Abstract
In this work arc welding simulation in the course of welding of austenitic steel has been accomplished. The simulation of butt welds of the sheet specimens with the force-cooling of high temperature area by the hard carbon oxide has been carried out. The influence of distance between the arc and cooling area on the stresses and deformations of austenitic steel specimens has been estimated. The stresses and deformations value in the different welding conditions has been calculated with non-simmetric three-dimensional model of the heat source. The model had the heat flow distribution in double ellipsoid area as the Gaussian law. As a result it has been calculated the construction stresses and deformations as the functions of the distance between the arc and cooling area. These functions will permit to calculate the optimal welding conditions to minimize the deformations of welding sheet constructions.
