Problems solved by technology

The welding quality and welding efficiency are determined by the welding material and welding process, especially the welding material is the key to welding. At present, the composition of the flux-cored welding wire is unreasonable, resulting in small pores and cracks in the deposited metal. At the same time, the wear resistance, corrosion resistance and toughness still need to be improved.

Abstract

The invention discloses a high-toughness wear-resistant flux-cored wire which consists of a flux core and stainless steel skin covering the flux core. The flux core comprises the following raw materials: graphite powder, silicon powder, magnesium powder, nickel powder, titanium powder, titanium dioxide powder, titanium boride powder, iron oxide powder, zirconium oxide powder, aluminum-strontium alloy powder, electrolytic manganese powder, ferromolybdenum powder, ferroniobium powder, ferrovanadium powder, rare earth ferroalloy powder, carbonate, metal fluoride, and the balance reduced iron powder and unavoidable impurities. The high-toughness wear-resistant flux-cored wire has the advantages that splashes are small, smoke is little, the forming is good, deslagging is easy, deposited metal is compact in structure, no pores or flaws appear, the high-toughness wear-resistant flux-cored wire is combined with parent metal well and is stable in performance, the deposited metal has good wear resistance, corrosion resistance and high toughness, and the high-toughness wear-resistant flux-cored wire has good economic benefits.

Description

technical field [0001] The invention relates to the field of welding wire technology, in particular to a high-toughness wear-resistant flux-cored welding wire. Background technique [0002] As a common metal welding material, flux cored wire is widely used in aerospace, automobile manufacturing, construction, bridge, petrochemical and other fields. The welding quality and welding efficiency are determined by the welding material and welding process, especially the welding material is the key to welding. At present, the composition of the flux-cored welding wire is unreasonable, resulting in small pores and cracks in the deposited metal. At the same time, it needs to be improved in terms of wear resistance, corrosion resistance and toughness. Flux-cored welding wire has been widely used in the automobile manufacturing industry, the welding of structural parts in high-rise buildings, the offshore platform manufacturing industry and its oil and gas pipelines.
