Problems solved by technology

However, due to the high carbon content of such welding materials, they often have poor resistance to welding cracks and low toughness.
[0004] In the prior art, submerged arc welding wire or special flux-cored welding wire and flux for hard surface surfacing are mostly used in surfacing welding, which will cause the following problems: 1. The hardness of the surfacing layer is uneven and unstable; 2. There are cracks; 3. , wear resistance is not good, the cost is high, the above problems all restrict the development of hard surface surfacing flux cored wire

Abstract

The invention belongs to the technical field of bead weld materials and specially relates to a solder wire with a rear earth reinforced bead weld flux core. According to the solder wire with the rearearth reinforced bead weld flux core, the flux core is prepared from the following chemical components including, by weight, 0.2-0.6% of carbon, 0.4-0.8% of ferroboron, 1-1.5% of ferrochrome, 1-3% offerro-molybdenum, 0.2-1.0% of sodium fluoride, 0.2-1.5% of potassium titanate, 0.2-0.8% of yttrium-base heavy rare earth ferrosilicon, 0.8-1.8% of ferromanganese and the balance Fe. The solder wire has good abrasion resistance and red hardness and is capable of preventing stripping of bead weld layers.

Description

technical field [0001] The invention belongs to the technical field of surfacing welding materials, and in particular relates to a rare-earth reinforced 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 th...
