Advantages of the process of welding without short-circuiting with double gas shielding of the arcing zone are shown. The arc is shielded by argon, and the weld pool - by carbon dioxide gas, fed through two concentrically located nozzles. Calculation of arc radius in its largest cross-section was performed. Calculation of weld pool length allows determination of the diameter of nozzle for carbon dioxide feed. Application of higher welding parameters requires increasing the diameter of nozzles, which can be calculated by similar procedures.
