Hot-melting welding material

Abstract

The invention discloses a hot-melting welding material. The hot-melting welding material is prepared from the following raw materials in parts by weight: 6-8 parts of copper oxide, 7-10 parts of aluminum, 1-4 parts of magnesium oxide, 6-9 parts of methanol, 40 parts of deionized water, 5-11 parts of o-hydroxybenzoic acid, 2-6 parts of Mo, 6-10 parts of alcohol, 0.5-3 parts of dibromosuccinic acid, 2-4 parts of soda ash, 8-13 parts of chromium metal, 4-7 parts of quartz, 5-10 parts of phenolic resin, 2-4 parts of metal nickel, 6-11 parts of polyethylene ethanol and 5-8 parts of organic acid. The hot-melting welding material has the beneficial effects of good weldability, uniform and smooth welding and high welding quality, and is harmless to environment.

Description

technical field [0001] The invention relates to a hot-melt welding material. Background technique [0002] Hot melt welding is to use the reaction between metal compounds to generate high temperature, through the overheated molten metal, directly or indirectly heat the work, and form a certain shape and size in the cavity of the special graphite abrasive tool, which meets the process requirements. Fusion welding joints . When welding, the ends of the two workpieces to be welded are fixed in the mold in advance, and then the mixture of aluminum powder and iron oxide powder (called thermite) is heated in the crucible to cause a reduction exothermic reaction. However, hot-melt welding is easy to make the welding material brittle, and the tensile stress parameters of the metal material may also appear. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the problem to be solved by the present invention is to provide a hot-melt welding material wit...
