Description

Technical Field

[0001] This utility model relates to the field of solid welding wire, specifically a high-strength steel anti-breakage solid welding wire. Background Technology

[0002] In the process of steel structure welding, two types of welding wire are required: flux-cored wire and solid wire. Solid wire is a welding material made of metal wire or rod, usually used to connect two or more metal parts together. They are widely used in industry, construction and manufacturing, especially in the welding of materials such as steel and aluminum. The main difference between solid wire and flux-cored wire lies in their internal structure: solid wire is solid inside and does not contain flux. They usually use external flux to protect the molten pool and the base material. During the welding process, the flux melts and disperses around the weld. Most existing solid wires are integrally formed and have a smooth surface, which can lead to breakage during use or winding, thus increasing cost. Therefore, it is necessary to provide a solid wire that is resistant to breakage. Utility Model Content

[0003] This utility model provides a high-strength steel anti-breakage solid welding wire, aiming to solve the problem that the overall anti-breakage performance of existing solid welding wires needs to be improved, which increases cost.

[0004] To achieve the above objectives, this utility model provides a high-strength steel anti-breakage solid core welding wire, including a welding wire assembly;

[0005] The welding wire assembly includes an outer tube, a first inner tube installed inside the outer tube, a second inner tube installed inside the first inner tube, a third inner tube installed inside the second inner tube, and a core wire installed inside the third inner tube.

[0006] As a preferred embodiment of this utility model, the inner wall of the outer tube is provided with a plurality of first strip grooves at equal intervals, and the side surface of the first inner tube is fixedly connected with a plurality of first side strips, and the plurality of first side strips are all snapped into the inside of the first strip grooves.
