Problems solved by technology

However, due to the high temperature of the molten alloy during welding, the problem of welding slag splashing is prone to occur due to the large temperature difference when it is in contact with the weldment. The welding rods with different fluxes have different spattering degrees, but welding slag splashing cannot be avoided.
Welding slag splash may cause harm to the health of welding operators, and may also cause fire hazards in the welding place

Abstract

The invention belongs to the technical field of metal welding materials, and particularly relates to a low-splashing type safe welding rod. The welding rod is formed by a metal core wire and a first welding flux layer wrapping the metal core wire, and a second welding flux layer is coated to the exterior of the first welding flux layer. The first welding flux layer is mainly prepared from high carbon ferro-chrome, mid-carbon ferromanganese, tungsten carbide, nickel powder, rutile, silicon iron, ferrovanadium, magnesium oxide, fluorite, fluoride and an adhesive; the granularity of all raw materials are 80 meshes or above, and the second welding flux layer is mainly prepared from rosin and Vaseline. In the welding process, the fusion and volatilization process of second welding flux will reduce the temperature of welding slag generated by first welding flux, the adhesion degree of the welding slag is increased, the two kinds of welding flux is used, the welding slag splashing degree andscope are obviously reduced when the welding rod is welded, and the safety performance of the welding rod is improved.

Description

technical field [0001] The invention belongs to the technical field of metal welding materials, and in particular relates to a low-splash safety welding rod. Background technique [0002] Welding is a manufacturing process and technology that uses heat, high temperature or high pressure to join metal or other thermoplastic materials such as plastics. Electric welding is a kind of welding technology. Electric welding can not only be used to connect metal parts, but also modify the surface of metal parts to obtain the required cladding layer with special properties such as wear resistance, heat resistance or corrosion resistance. The technology is widely used in industrial fields such as mining, metallurgy, agricultural machinery, construction, railway, petroleum and chemical industry, and has extremely high economic and social benefits. [0003] Electrode is a metal strip that is melted and filled at the junction of welded parts during electric welding. It is mainly composed...
