Abstract
Description
Technical Field
[0001] This utility model belongs to the field of welding wire production technology, and in particular relates to a welding wire cleaning device. Background Technology
[0002] Flux-cored welding wire, also known as powder-cored welding wire or tubular welding wire, can be divided into two main categories based on the shielding method: gas-shielded and non-gas-shielded. Similar to solid-cored welding wire, the surface of flux-cored welding wire is made of materials with good plasticity, such as low-carbon steel or low-alloy steel. Its production process typically involves first rolling a steel strip into a U-shaped cross-section, then filling the U-shaped steel strip with welding powder prepared in a specific ratio, compacting it using a rolling mill, and finally drawing it to produce flux-cored welding wires of different specifications.
[0003] In the drawing process of flux-cored welding wire, drawing powder is used to lubricate the wire to reduce frictional resistance and ensure smooth drawing. However, after the drawing process, a large amount of drawing powder remains on the surface of the welding wire. This not only causes the surface of the welding wire to become dull in color, reducing the appearance quality of the product, but more seriously, the hydrogen element contained in the drawing powder can diffuse into the weld during the welding process, causing defects such as porosity and cracks in the weld, which greatly affects the welding quality.
[0004] Furthermore, during welding, the wire drawing powder gradually adheres to the surface of the contact tip, forming an insulating layer between the contact tip and the welding wire. This hinders current transmission and reduces conductivity. Severe adhesion can cause arc extinction during welding, interrupting the welding process, reducing production efficiency, and increasing production costs.
[0005] To effectively solve the series of problems caused by residual wire drawing powder, it is urgent to develop a high-efficiency welding wire cleaning device. Utility Model Content
