Summary:Title screen
In the given paper we consider the impact of wind velocity upon the active shielding gas flow and changes of thermal processes in the MAG welding area. The authors completed numerical simulation of consumable electrode welding under traditional and two-jet gas shielding. It was established that application of two-jet gas shielding for MAG welding increases the hardness of the shielding gas jet and reduces wind-related displacement of thermal fields in the welded item. This ensures more qualitative shielding of the welding area under the windy conditions and uniform heat distribution in the welded item which leads to more homogeneous structure of weld and HAZ metal in comparison to the traditional (one-jet) gas shielding.
