Hot melting welding material

Abstract

The invention relates to a hot melting welding material, and belongs to the technical field of welding materials. The hot melting welding material comprises the following raw materials of, by weight,30-50 parts of copper oxide, 5-10 parts of metallic aluminium powder, 1-3 parts of magnesium oxide, 3-9 parts of o-hydroxybenzoic acid, 4-8 parts of ethyl alcohol, 0.5-2 parts of dibromosuccinic acid,2-5 parts of cuprous oxide, 1-4 parts of sodium carbonate, 6-10 parts of metallic zinc powder, 2-8 parts of quartz, 3-8 parts of phenolic resin, 1-3 parts of metal fluorine powder and 4-10 parts of polyethylene glycol. The welding point has good stability and high surface evenness and has certain toughness compared with an existing brittle welding line, the possibility of fracture is reduced, theuniformity of the welding point is improved, and the number of times of repeated welding is reduced.

Description

technical field [0001] The invention relates to a hot-melt welding material, which belongs to the technical field of welding materials. Background technique [0002] Welding material refers to the general term for materials consumed during welding, such as welding rods, welding wires, metal powders, fluxes, gases, etc. The welding industry is developing rapidly, mainly divided into argon welding, CO 2 Welding, oxy-cutting, electrode arc welding, robotic welding and other methods [0003] Hot melt welding is a kind of exothermic welding. Exothermic welding is a simple, high-efficiency and high-quality metal joining process. It uses the chemical reaction heat of metal compounds as a heat source, through superheated (reduced) molten metal, directly Or indirect heating work, forming a certain shape and size in the cavity of a special graphite mold, and a welded joint that meets the engineering requirements. At present, exothermic welding has generally replaced the previous me...

Problems solved by technology

[0004] The existing hot-melt welding weld marks are prone to unevenness, which will lead to cracks in the later stage, the welded surface is uneven, and the uniformity is inconsistent, and subsequent problems such as partial area fractures will occur due to stress and other problems; They are relatively brittle, have no toughness, and have a small range of applications, which limits the application of hot-melt welding
