Description

technical field [0001] The invention relates to the technical field of welding wire surface coating, in particular to a structurally stable wear-resistant coating welding wire and a preparation method thereof. Background technique [0002] China has now become the world's largest producer of welding materials. In terms of welding wire, for low-carbon steel and low-alloy steel welding wire, there are problems such as plugging and wear of the contact tip, and the role of the surface coating of the welding wire is particularly critical. At present, there are many kinds of wear-resistant welding wires in the domestic market, but the surface coatings of these products have the disadvantages of low wear resistance coefficient, and the wear-resistant layer is easy to crack and peel off after being impacted. Contents of the invention [0003] Based on the technical problems in the background technology, the present invention proposes a structurally stable wear-resistant coated we...
