Abstract

The invention discloses a surfacing welding electrode. The surfacing welding electrode consists of a welding core and a coating, wherein the coating is coated on the outer wall of the welding core; the welding core comprises the following chemical components in percent by weight: 0.6-1.4% of C, 0-1.0% of Mn, 0.3-2.0% of Si, 28-35% of Cr, 3.2-6.5% of W, 0-2.0% of Fe and the balance of Co; and the coating adopts a TiO2-Si02-CaO slag system and comprises a slag making agent, a gas making agent and an alloy agent. All the components are as follows: the slag making agent comprises the following components in percentage by weight: 35-50% of rutile and titanium white (TiO2), 10-20% of mica, feldspar and bentonite (SiO2) and 5-12% of fluoride, wherein the fluoride comprises at least one of NaF and MgF2, CaF2 and BaF2; the gas making agent comprises the following component in percentage by weight: 12-22% of carbonate comprising CaCO3, MgCO3 and BaCO3; and the alloy agent comprises the following component in percentage by weight: 10-18% of manganese, chromium and nickel. In the welding material, a drill is utilized as a base body, so that the surfacing metal can still maintain good wear resistance and corrosion resistance when in working at the temperature of about 650 DEG C, and simultaneously the welding operation is good.

Description

technical field [0001] The invention relates to the field of welding materials, in particular to a hard surface wear-resistant surfacing electrode. Background technique [0002] Overlay welding is a welding process that deposits a layer of wear-resistant, corrosion-resistant, heat-resistant metal layers on the surface or edge of the workpiece. Surfacing welding can improve the service life of parts, use materials reasonably, improve product performance and reduce costs, and has significant economic benefits. In industrial production, welding technology such as surfacing welding is developing rapidly. [0003] Surfacing welding materials are divided into three categories: manual welding rods, welding wires, and strip welding strips. Among the hardfacing surfacing materials in my country, surfacing electrodes account for about 70%, surfacing welding wire accounts for about 25%, and welding strips account for about 5%. It can be seen that the surfacing electrode plays an impo...
