Problems solved by technology

In the process of steel structure processing and welding, the temperature is often relatively high. Many welding materials may be overheated, embrittled, hardened or softened in the weld seam and heat-affected zone after welding due to the difference in workpiece material, welding material, and welding current. Phenomenon, it also reduces the performance of the weldment and deteriorates the weldability

Abstract

The invention discloses a high-temperature welding material which consists of the following raw materials of , by weight, 2-3 parts of magnesium oxide, 3-6 parts of iron, 3-5 parts of aluminum, 5-7 parts of sodium carbonate, 3-5 parts of quartz, 1-3 parts of nickel, 0.5-1 part of carbon, 0.3-0.6 part of silicon, 2-4 parts of cobalt, 0.5-1 part of tungsten, and 0.01-0.05 part of chromium, wherein the grain size of the raw materials is 10-50 meshes. The high-temperature welding material is excellent in hot crack resistance, and has good anti-high-temperature-creep strength and ablation resistance; and a welded interface is high in strength.

Description

technical field [0001] The invention belongs to the technical field of steel structure processing, and in particular relates to a high-temperature welding material. Background technique [0002] The welding process is a manufacturing process and technology for joining metal or other thermoplastic materials by heating. The welding material is mainly determined according to the material, chemical composition, structure type of the weldment, and welding performance requirements of the workpiece to be welded. In the process of steel structure processing and welding, the temperature is often relatively high. Many welding materials may be overheated, embrittled, hardened or softened in the weld seam and heat-affected zone after welding due to the difference in workpiece material, welding material, and welding current. The phenomenon also reduces the performance of the weldment and deteriorates the weldability. Therefore, what kind of welding material to choose can withstand high ...
