Abstract
New approach to the solution of problem of a spattering decrease during CO₂ welding is suggested. It consists in the fact that short circuits are created continuously with the help of electronic methods according to a preset program. A pilot model of the welding equipment using IGBT transistor is manufactured. The application of the mentioned approach allows the metal spattering to be decreased by 40-50 %.
Keywords: consumable electrode welding, shielding gases, spatter, metal transfer control
