Abstract

The invention belongs to the field of welding materials, and particularly relates to a wear resistant surfacing flux-cored wire. The wear resistant surfacing flux-cored wire is formed by rolling and drawing an H08A steel belt which wraps powder. A flux core comprises, by mass, 5-10% of titanium dioxide, 2-8% of feldspar, 1-5% of cryolite, 2-5% of zircon, 2-8% of silicon iron, 5-10% of ferromanganese, 30-50% of chromium metal, 5-10% of ferrotitanium, 3-8% of ferroniobium, 3-10% of chromium nitride, and the balance iron powder. The flux-cored wire is suitable for CO2 gas shielded surfacing, the fume forming rate of welding is small, the wear resistance is high, the average hardness of a surfacing layer reaches 40-56, the rigidity is high, stiffness is excellent, and the wear resistant material is capable of resisting large impact.

Description

technical field [0001] The invention belongs to the technical field of welding materials, and in particular relates to a wear-resistant surfacing welding flux-cored welding wire. Background technique [0002] Surfacing welding, as an economical and rapid process method for surface modification of materials, is more and more widely used in the manufacture and repair of parts in various industrial sectors. In order to play the role of the surfacing layer most effectively, it is hoped that the surfacing welding method adopted has a small dilution of the base metal, a high deposition speed and excellent performance of the surfacing layer, that is, high-quality, high-efficiency, low-dilution rate surfacing welding technology. [0003] At present, the commonly used wear-resistant surfacing materials contain high carbon and alloy elements, mainly using carbon and chromium, titanium, vanadium, niobium, etc. to form carbide hard points to increase the hardness of the surfacing layer...
