Manual arc welder heat melting soldering material

Abstract

The invention provides a manual arc welder heat melting soldering material, formed by copper oxide, calcium oxide, cuprous oxide, quartz, phenolic resin, chrome, and nickel. The soldering material isgood in weldability, welding is uniform and smooth, and welding quality is high, and the soldering material has no harm on environment. The soldering material is suitable for a manual arc welder, andwelding quality is good. The soldering material is good in mechanical property, and crack and peeling would not occur. The soldering material has good corrosion resistance, and adding of the calcium oxide and the quartz synergistically increases the corrosion resistance, and service life of a weld assembly is prolonged.

Description

Technical field [0001] The invention relates to the technical field of welding materials, and more specifically to a manual arc welding machine hot-melt welding material. Background technique [0002] Hot melt welding is the use of the reaction between metal compounds to generate high temperature, through the overheated molten metal, direct or indirect heating work, a certain shape and size are formed in the cavity of a special graphite abrasive tool, and a welded joint that meets the process requirements . 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 and exothermic reaction. However, hot-melt welding tends to make the welding material brittle, the tensile stress parameters of metal materials, and at the same time, the phenomenon of welding nodules or unevenness of the welding ring may occur. Summary of the...
