Preparing method of environment-friendly type stainless steel welding wire not plated with copper

Abstract

The invention discloses a preparing method of an environment-friendly type stainless steel welding wire not plated with copper and belongs to the technical field of welding wire machining. A degreasing solution is prepared by using sodium hydroxide, sodium carbonate, sodium phosphate dodecahydrate and sodium silicate as raw materials, a low-carbon steel wire is soaked in the degreasing solution for ultrasonic washing after being polished, and the low-carbon steel wire is connected with a power supply with a pure nickel bar, placed in an electroplating solution prepared by mixing nickel sulfate hexahydrate, nickel chloride, titanium dioxide and the like for electroplating, and dried after being fully electroplated so as to obtain the environment-friendly type stainless steel welding wire not plated with copper. The preparing method obviously improves the ductility, toughness and high temperature resistance of the welding wire by electroplating one layer of nickel and titanium dioxide on the surface of the low-carbon steel wire, avoids the problems of environment pollution and physical health hazards, caused in an original welding wire copper plating production process, improves the safety of a welding wire preparing process, and has wide application prospects.

Description

technical field [0001] The invention discloses an environment-friendly preparation method of copper-free stainless steel welding wire, which belongs to the technical field of welding wire processing. Background technique [0002] In the prior art, there is a serious environmental pollution problem in the copper plating production process of welding wire. No matter the plating solution, exhaust gas, or waste liquid will bring great harm to human health and the environment. At the same time, during the use of copper plating welding wire The copper vapor produced in the air will also bring another kind of harm to the human body. The proposal of non-copper-plated welding wire is based on the above problems. In its production process, although the copper-plating process is removed, an environmentally friendly production process is adopted to ensure that the non-copper-coated welding wire has reliable anti-corrosion performance, and even has some corrosion resistance. Special per...

Problems solved by technology

[0004] The technical problem mainly solved by the present invention: In view of the defect that the copper plating layer causes serious pollution to the environment and poor toughness and yield performance during the use of the current traditional welding wire, the present invention provides an environmentally friendly copper-free welding wire The preparation method of stainless steel welding wire, the present invention uses sodium hydroxide, sodium carbonate, sodium phosphate dodecahydrate, and sodium silicate as raw materials to prepare a degreasing liquid, and ultrasonically cleans the polished low-carbon steel wire in the degreasing liquid, Then connect the pure nickel strip to the power supply and place it in the electroplating solution prepared by mixing nickel sulfate hexahydrate, nickel chloride, titanium dioxide, etc. for electroplating. After the electroplating is complete, it will be dried to obtain an environmentally friendly copper-free stainless steel welding wire. The present invention adopts A layer of nickel and titanium dioxide is electroplated on the surface of the low-carbon steel wire, which significantly improves the plasticity, toughness and high temperature resistance of the welding wire. Has broad application prospects
