Welding material used for ring-type electric arc welder

Abstract

The invention provides a welding material used for a ring-type electric arc welder. The material is characterized by comprising copper oxide, aluminum, magnesium oxide, o-hydroxybenzoic acid, quartz,dibromosuccinic acid, phenolic resin, and nickel. The welding material is good in weldability, uniform and smooth in welding, and high in welding quality, and has no harm on environment, and is suitable for a ring-type electric arc welder. The welding material is good in welding quality, good in mechanical properties, and would not crack or peel, and has high corrosion resistance. Adding of quartzimproves corrosion resistance of the material.

Description

technical field [0001] The invention relates to the technical field of welding materials, in particular to a welding material used for a ring type arc welding machine. Background technique [0002] Welding is a connection method in which two separate metal objects are bonded between atoms (or molecules) by appropriate means. The arc welding machine is a special equipment used to provide current and voltage energy and has output characteristics suitable for the welding method. [0003] And 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 requirements of the process. head. 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 t...

AI Technical Summary

Problems solved by technology

However, hot-melt welding is easy to make the welding material brittle, and the tensile stress parameters of the metal material may also cause fusion tumors or uneven welding rings.
