Abstract

A set of various factors and phenomena defines the quality of welded joints. This is especially noticeable for outdoor welding. A numerical simulation of welding processes with consumable electrode with traditional and two-jet gas shielding was carried out to study the influence of wind speed on the movement of the shielding gas (CO2) and the change of thermal processes in the heat affected zone. It is established that the use of two-jet shielding in welding with a consumable electrode leads to an increase in hardness of the shielding gas stream and lower offset of thermal fields in the welded product in the wind direction. It testifies to a better quality of shielding and smaller probable changes in symmetry of structure formation and mechanical properties of the heat affected zone.
