Description and Features:

The main and fundamental feature of flux wire is weld porosity that is caused by contact of the liquid metal with atmospheric gases that are absorbed by the liquid metal and segregate during its crystallization. Porosity in the weld metal contributes mainly by nitrogen (N). To estimate porosity zone it is important to look after the content of nitrogen, the limit value of it is 0.025%.

In the national economy flux welding wire E71T-1 applied in the field of building and bridge construction, large parts in machinery, vessels of sheet metal and shipbuilding. In construction, flux welding wire in CO2 used in the manufacture of building frames of converter and rolling mills, blast furnace complex structures, metal hopper and unloading ramps, sloping superstructures of bridges, transportation galleries, etc.
