Overview of SAW Flux-cored Wire Hardfacing Technology
SAW Flux-cored Wire for Wear Plate Hardfacing
Submerged Arc Welding (SAW) flux-cored wire for wear plate hardfacing is a specialized welding consumable designed for the production and reparation of wear-resistant steel plates. Hardfacing technology deposits a layer of high-hardness, high-wear-resistant alloy material on the surface of low-carbon steel or low-alloy steel substrate through SAW process, combining the good toughness and weldability of the substrate with the excellent wear resistance of the surfacing layer, which effectively reduces production costs compared with using full wear-resistant castings or alloy steels.
The SAW process for hardfacing has unique advantages compared with other surfacing methods, including high deposition rate, deep molten pool penetration, smooth weld formation, automatic operation adaptability and effective slag protection that avoids splatter and porosity. Flux-cored wire, different from solid wire, can flexibly adjust the alloy composition inside the powder core to meet different wear resistance requirements, making it the most widely used consumable in mass production of wear plates in industries such as mining, cement, construction and metallurgy.

Hardfacing welding wire
Hardfacing welding wire
Hardfacing welding wires are filler metal materials used in the hardfacing process. With electric arcs or other welding heat sources, the wires are melted and deposited onto workpiece surfaces to form cladding layers featuring excellent wear resistance, corrosion resistance, high temperature resistance and other special properties. This restores the original dimensions of workpieces, improves their surface performance and extends their service life. Compared with replacing workpieces entirely, hardfacing only costs 1/5 to 1/3 of the price of new parts, which greatly cuts production and operation costs. Therefore, this technology is widely applied to the repair and strengthening of components in mining machinery, petrochemical industry, metallurgy, power engineering, construction machinery and other field
