Abstract

The invention provides a structural steel welding rod and a method for preparing the same. The structural steel welding rod comprises welding cores and coating. The coating wraps the welding cores. The coating comprises, by weight, 5-35 parts of titanium dioxide powder, 20-27 parts of reduction titanium, 7-8.5 parts of medium manganese, 7-10 parts of lime mud, 5 parts of mica, 3 parts of argil, 2-4 parts of feldspar, 7-8.5 parts of marble, 0-2 parts of wood meal, 1-3 parts of celluloses, 0-30 parts of rutile and 0-5 parts of illite. The method includes steps of adhesive adding and wet mixing, press coating and drying. The diameters of the welding cores are 2-4 mm. The structural steel welding rod and the method have the advantages that processes for manufacturing the structural steel welding rod are simple, the coating and the welding cores are good in connection performance, the structural steel welding rod generates little smoke and is low in spark splashing during use, and welded joints are attractive and are high in smooth finish; the structural steel welding rod is good in secondary arc strike property and is environmentally friendly and safe during use, slag is easy to remove, and the work efficiency can be greatly improved.

Description

technical field [0001] The invention belongs to the technical field of welding materials, and more specifically relates to a structural steel welding rod and a preparation method for making the welding rod. Background technique [0002] The welding rod is a metal strip that is melted and filled at the joint of the welding workpiece during gas welding or electric welding. It consists of two parts, the coating and the welding core. Relying on the melting of the coating and adding it to the weld as a filler metal, it becomes the main component of the weld metal. Now some welding rods have a lot of smoke and sparks during use, and they emit more pollutants, causing environmental pollution. It is difficult to strike the arc twice at the weld seam, and it is difficult to remove the weld slag. It needs to be removed by knocking. The operation is complicated, which is a waste of time and results in low work efficiency. Contents of the invention [0003] The purpose of the presen...
