Abstract

The invention discloses a wear-resistant manual surfacing electrode. The wear-resistant manual surfacing electrode is composed of, by weight, 10-20 parts of ferroboron, 3-8 parts of silicon, 2-6 parts of barium carbonate, 5-12 parts of carbon, 4-9 parts of high carbon ferro-chrome, 2-5 parts of nickel powder, 3-8 parts of ferrotitanium, 5-14 parts of cellulose, 6-8 parts of amorphous graphite and 10-12 parts of rutile. Because a substrate of the surfacing electrode is made of cobalt, good wear resistance and good corrosion resistance can stilled be kept when the surfacing electrode works under the temperature of about 650DEG C; meanwhile, the surfacing electrode is good in welding operation performance and has the advantages that electric arcs are stable, arc light is soft, spatter is small, slag detachability is good, the appearance of weld joints is attractive and welding performance is good.

Description

technical field [0001] The invention belongs to the field of welding materials, in particular to an electrode, in particular to a wear-resistant manual 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. 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 electro...
