Abrasion-resistant flux-cored wire

Abstract

The invention discloses an abrasion-resistant flux-cored wire. The abrasion-resistant flux-cored wire comprises a carbon steel sheath and powder filled into the carbon steel sheath. The powder comprises 0.03 to 0.09% of Cr, 0.05 to 0.11% of Mo, 1.1 to 1.7% of Mn and 1.3 to 1.9% of Si, based on the total weight of the wire.The abrasion-resistant flux-cored wire has following beneficial effects: by rigidly controlling components and the content of powder, an electric arc is stabilized and the amount of welding slag on the surface of a welding pass is greatly decreased, thereby effectively controlling the amount of welding slag; the flux-cored wire is added with C so that strength of welded metal is ensured and abrasion-resistant degree is further improved; the flux-cored wire is added with Si in order to decrease the oxygen content in deposited metal and improve mobility of deposited metal; and by utilizing the flux-cored wire, good stability is achieved and a welding surface becomes complete and neat.

Description

technical field [0001] The invention relates to the technical field of metal welding materials, in particular to a wear-resistant flux-cored welding wire. Background technique [0002] Flux-cored welding wire is also called tubular welding wire or welding material for various purposes (wear resistance, high strength, heat resistance, corrosion resistance, low temperature resistance), etc. Because its alloy composition can be adjusted flexibly and conveniently, many varieties of flux cored wire cannot be smelted and rolled by solid wire. At the same time, due to the characteristics of the product structure, the welding process performance and welding efficiency of flux-cored welding wire have advantages compared with solid-cored welding wire and manual welding rod. [0003] The existing welding wires are relatively successful in terms of stability, but their wear resistance and the integrity of the welded parts are relatively unsatisfactory. Therefore, the inventors provide ...

Problems solved by technology

[0003] The existing welding wires are relatively successful in terms of stability, but their wear resistance and the integrity of the welded parts are relatively unsatisfactory. Therefore, the inventors provide a kind of wear resistance by studying the composition and content of the powder in the flux-cored wire. Strong, flux-cored wire that can effectively suppress the amount of welding slag in the welding process and ensure that the welding surface is complete and clean
