Sažetak

The paper presents up-to-date achievements in application of a new method of arc welding of various rail profiles, defined 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 flux-cored wire. The method does not require protective atmosphere or usage of additional powdered materials (flux). The process is semiautomatic. Except the standard power source, the welding equipment has been designed by the E.O. Paton Electric Welding Institute.
