Detailed description

- NB-E71T-1 flux cored welding wire has the basic advantage of improving the metallurgical function of the welding process and the mechanical properties of the filler layer through the alloying elements contained in the welding drug.

- The inner core of the flux has the effect of forming a thin layer of slag to protect the molten metal droplets and welding puddles, provide the reducing agents, provide the metal elements necessary for metallurgy and improve weld metal properties.

- NB-E71T-1 has low Carbon content, average Manganese and Silicon content, sulfur impurities and extremely small phosphorus to create welds with high strength and toughness.

APPLICATION:

E71T-1 is applied in industries such as:

- Steel Buildings

- Ship and hydropower plants

- Structure of bridges, pressure vessels, buildings and tanks ...

ADVANTAGES COMPARED TO TRAN WELDING WIRE:

- Stable arc, less spatter, less smoke than bare welding wire

- Tensile strength as well as higher welding performance

- Better quality weld surface than bare welding wire
