Problems solved by technology

Due to defects in the batching and material selection of the existing titanium-calcium welding rods, there are the following deficiencies in practical engineering applications: the molten droplets of the arc are not fine enough, the sparks are large, the physical properties of the liquid slag are poor, the properties of the deposited metal and The toughness is not stable enough, especially wood powder and cellulose are used as gas-generating agents in the electrode coating, which not only wastes a lot of wood resources, but also has a high concentration of smoke and dust, high content of dust and harmful substances in welding applications, and the smell is unpleasant, which is easy to cause Hazards to people and the environment also limit applications

Abstract

The low-dust environment-protecting type carbon steel electric welding rod is made up by using reduced ilmenite, rutile, mica, white mud, medium manganese, marble, clay, pyrauxite, feldspar, wollastonite and natural cereal skin as main raw material. Said electric welding rod possesses excellent welding property, high deposition rate, can reduce welding smoke and dust, and is favorable for protecting environment, and its cost is low.

Description

technical field [0001] The invention relates to a carbon steel welding rod for arc welding. Background technique [0002] With the rapid development of the metal manufacturing and processing industry, the technical requirements for the welding electrodes used in the welding process are also getting higher and higher. In the known technology, existing carbon steel welding rods such as E4303 and 4313 carbon steel welding rods with titanium-calcium type coating mainly use rutile, titanium dioxide, reduced ilmenite, medium carbon ferromanganese, white mud , mica, marble, clay, phylloparaffin, wood flour, cellulose and other raw materials. Due to defects in the batching and material selection of the existing titanium-calcium welding rods, there are the following deficiencies in practical engineering applications: the molten droplets of the arc are not fine enough, the sparks are large, the physical properties of the liquid slag are poor, the properties of the deposited metal and...
