Problems solved by technology

[0003] The surfacing welding electrodes widely used at present all have good mechanical properties and mechanical properties, but the tensile properties and yield strength still need to be further improved, and more welding slag will be generated during preparation, which is difficult to clean, and the moisture content of the coating is relatively high. High, and the formed weld is easy to crack

Abstract

The invention discloses a surfacing welding rod and a preparation method thereof. The welding rod comprises a core wire and a coating. The core wire is selected from an H08A or H08E low-carbon steel core wire. The coating comprises, by weight, 40-60 parts of marble, 10-20 parts of fluorite, 5-12 parts of atomized silicon iron, 0.2-1.5 parts of silicon carbide, 8-16 parts of nano-iron powder, 10-20 parts of titanium dioxide, 5-12 parts of ferromanganese, 3-10 parts of chrome powder, 3-6 parts of nickel powder, 10-25 parts of sepiolite, 8-18 parts of sodium silicate, 2-6 parts of light calcium carbonate and 0.5-3 parts of a plasticizer. The preparation method comprises the steps of sepiolite fermentation, alloy material sintering, dry coating preparation and compression molding. The surfacing welding rod has excellent tensile strength, toughness and yield strength, the amount of welding slag generated in the preparation process is small, fusion is complete, high efficiency, energy saving and low pollution are achieved, and the working efficiency of welding is improved.

Description

technical field [0001] The invention relates to the technical field of welding materials, in particular to a surfacing welding electrode and a preparation method thereof. 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. The use of surfacing welding to manufacture products or repair mechanical parts can not only restore the original size of the parts, but also further improve the wear resistance and compression resistance of the workpiece, which is important for reducing production...
