Abstract
This paper analyzes, from the metallurgical aspect, the quality of the new flux-cored wire intended for the MAG welding process in function of changes in shielding gas composition and changes in welding parameters. The results of comparative analysis of the microstructure of the weld metal and Heat Affected Zone (HAZ) allow drawing conclusions about the feasibility of introducing a new quality flux-cored wire in industrial applications.
