Strong current high-purity welding wire rust removal process

Abstract

The invention relates to a welding wire processing process, in particular to strong current high-purity welding wire rust removal process. The strong current high-purity welding wire rust removal process is characterized by comprising the following steps: washing a welding wire with cold water for two times, washing with hot water for one time, passing through an electrolytic cell filled with a sulfuric acid solution with an electrode voltage of 12 v, a current of 500 mA and a concentration of 180-190 g / l at a speed of 8-9 m / s, taking out and then washing with cold water for one time. The strong current high-purity welding wire rust removal process has the benefits that on the premise of saving the cost and the resources to a maximum degree, the welding wire rust removal effect is good, the process is simple, the surface of the welding wire is not affected, the surface of the welding wire after rust removal is clean and bright in color, the follow-up treatment and processing of the welding wire are facilitated, and the quality of the welding wire is greatly improved.

Description

(1) Technical field [0001] The invention relates to a welding wire processing technology, in particular to a high-current high-purity welding wire derusting technology. (2) Background technology [0002] Welding has been widely used in shipbuilding, vehicles, power station equipment, petrochemical, aerospace, heavy machinery, mining, metallurgy, construction machinery and other departments. The main production process of welding wire is: pretreatment - wire drawing - copper plating - layer winding. In the pretreatment process, rust removal is an extremely important part. At present, most manufacturers use mechanical rust removal. Although the process is simple and pollution-free, the surface of the processed welding wire is prone to scratches, the cleaning speed is slow, and it is not easy to use it in line with other equipment. Nowadays, although some manufacturers have begun to use chemical rust removal, due to the poor control of sulfuric acid content, voltage an...

Problems solved by technology

At present, most manufacturers use mechanical rust removal. Although the process is simple and pollution-free, the surface of the processed welding wire is prone to scratches, the cleaning speed is slow, and it is not easy to use with other equipment.

Nowadays, although some manufacturers have begun to use chemical rust removal, due to poor control of sulfuric acid content, voltage and current, not only the rust removal effect is not ideal, but also a waste of various resources, causing irreparable losses to the enterprise
