Abstract

The invention discloses a deep-penetration flux-cored stranded welding wire which comprises a flux core and an outer shell coated on the outer side of the flux core. The outer shell is made of cold-rolled low-carbon steel; and the flux core is prepared from the components in parts by weight: 20 to 30 parts of rutile, 5 to 10 parts of quartz, 1 to 5 parts of magnesia, 1 to 3 parts of aluminosilicate, 2 to 6 parts of cobalt powder, 1 to 4 parts of silicon carbide, 1 to 3 parts of manganese metal, 1 to 3 parts of molybdenum powder, 2 to 6 parts of iron powder, 0.5 to 4.5 parts of titanium powder,1 to 1.5 parts of aluminite powder, 0.2 to 0.6 part of hafnium powder, 1 to 2 parts of chromium powder, 0.5 to 1.5 parts of yttrium powder, 0.1 to 0.8 part of niobium powder, and 1 to 2 parts of tungsten powder. The invention discloses a preparation method of the deep-penetration flux-cored stranded welding wire. The preparation method of the deep-penetration flux-cored stranded welding wire comprises the following steps of processing cold-rolled low-carbon steel through a molding roller so as to form a U-shaped groove, mixing the flux core components, filling into the U-shaped groove, then rolling into a tubular shape, wiredrawing, and stranding to form the deep-penetration flux-cored stranded welding wire.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to a deep-penetrating flux-cored stranded welding wire, a preparation method thereof, and a welding method. Background technique [0002] Weathering steel has the ability to resist atmospheric corrosion because the alloying elements form a protective film on the surface of the steel substrate, which reduces the conductivity of the rust layer and hinders the rapid growth of the corrosion rust layer. The alloying elements that can improve the atmospheric corrosion resistance include nickel, chromium, copper and phosphorus. Among them, nickel is a relatively stable element. Adding nickel can change the self-corrosion potential of steel to a positive direction and increase the stability of steel. Chromium can form a dense oxide film on the surface of steel, improve the passivation ability of steel, and slow down the growth rate of rust layer. When copper is added to steel, the corrosi...
