Applications and Features

(1)    KFX-70T is suitable for welding 490N/mm² grade steel with flat and horizontal position.

(2)    High-deposition-rate of multi-layer fillet welding in horizontal and flat position.

(3)    High resistance against porosity when welded on primer-coated steel plates.

(4)    Uniform slag covering, regular weld toes, glossy bead surface and smooth lapping onto the preceding bead in multi-layer fillet welding.

(5)    Ideal for ship-building, tanks, bridges, steel structures and constructions.
