D. Bajic, University of Montenegro, Faculty of Mechanical Engineering, G. Vladimirovich Kuzmenko, E.O. Paton Electric Welding Institute, National Academy of Sciences Ukraine, I. Samardžić, J.J.Strossmayer university of Osijek, Mechanical Engineering Faculty in Slavonski Brod, Croatia The paper presents up-to-date achievements in application of a new method of arc welding of various rail profi les, defi ned as the Consumable Guide Enclosed Arc Welding (CGEAW). The welding process is based on a combination of specially prepared electrode, which core is identical in chemical composition to welded material, or belongs to its class, and self-shielded fl ux-cored wire. The method does not require protective atmosphere or usage of additional powdered materials (fl ux). The process is semiautomatic. Except the standard power source, the welding equipment has been designed by the E.O. Paton Electric Welding Institute.
