Abstract
The problem of modification of welding methods applied in industry, including application of new welding consumables, is challenging. It is shown that as an efficient welding consumable in arc methods of welding the dry ice (solid carbon dioxide) can be applied, which is facilitated by its unique properties, namely possibility of sublimation with formation of great amount of gases and very low temperature. Dry ice staying in welding zone forms a reliable protective gas environment of specific composition, which predetermines also a favorable arrangement of forces acting on the drop of electrode metal. In welding a stable mild arcing without excessive spattering with a good weld formation is observed. The ice sharply decreases residual welding deformations in welding of thin-sheet metal. In principle, the new arc welding method using consumable electrode, i.e. welding under dry ice, was offered, which is performed applying conventional welding equipment. Welding under dry ice can be used during manufacture, erection and repair of steel structures. The experiments showed that dry ice as an additional welding consumable is applicable in manual arc welding using covered electrodes, welding using flux-cored wire, in shielding gas and also during performance of surfacing works. 4 Ref., 4 Figures.
