Weld joint protection method for material with zinc-aluminum-magnesium coating, welding material and coating

Abstract

The invention particularly relates to a welding seam protection method for a material with a zinc-aluminum-magnesium coating, a welding material and a coating, and belongs to the field of welding seam protection. The welding seam protection method comprises the steps that a first spraying wire and a second spraying wire are fused, and a spraying material is obtained; spraying the spraying material on a target area to obtain a coating; wherein the first spraying wire contains a Zn element, and the second spraying wire contains a Mg element and an Al element. The first spraying wire containing the Zn element and the second spraying wire containing the Mg element and the Al element are fused and then sprayed to the target area, the coating is obtained, meanwhile, the spraying wires containing the Mg element and the Al element are not prone to being pulled and broken in the production process, the first spraying wire and the second spraying wire can be effectively sprayed, the coating containing the Zn element, the Al element and the Mg element is obtained, and therefore the coating can be used for coating the Zn element, the Al element and the Mg element. And the protection capability of the welding seam of the material with the zinc-aluminum-magnesium coating is improved.

Description

technical field [0001] The present application relates to the field of weld seam protection, in particular to a weld seam protection method, welding material and coating of a material with a zinc-aluminum-magnesium coating. Background technique [0002] At present, the preparation process of the main anti-corrosion structure is that the uncoated steel plate is first prepared into a steel structure through forming, welding and other processing procedures, and then the whole structure is anti-corrosion treated by hot-dip plating. However, this method requires hot-dip plating at the end user, and the process is complicated, not environmentally friendly, and it is not easy to protect large components. With the application of coated steel sheets, especially galvanized aluminum-magnesium steel sheets, some changes have taken place in the manufacturing process of steel structures. The new process uses zinc-aluminum-magnesium-coated steel sheets for forming and welding, and is used...
