Copper plating process for welding wire

Abstract

The invention discloses a copper plating process for a welding wire. The process comprises the following steps: providing a welding wire and drawing the welding wire; carrying out cleaning to remove a lubricant on the surface of the welding wire having undergone drawing; carrying out copper plating on the welding wire; drying the welding wire having undergone copper plating; sizing and polishing of the welding wire; and rolling up of the welding wire. According to the invention, after drawing of the welding wire, cleaning and direct copper plating are successively carried out, and there is no need for rolling up the drawn welding wire with an I-shaped wheel and subsequently carrying out wire supplying anew for copper plating, which enables a copper plating tank used for copper plating to be directly connected with a drawing machine used for drawing; thus, the speed of copper plating is increased by 2 to 3 times, production efficiency is improved, and considerable production cost is saved for enterprises.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to a welding wire copper plating process. Background technique [0002] Welding technology plays a very important role in shipbuilding, petrochemical, rolling stock, electric power, nuclear reactor and other fields. As an important branch of welding materials, welding wire is increasing year by year in the proportion of welding materials. [0003] Copper plating on the welding wire can make the welding wire have good conductivity and rust resistance. At present, the existing welding wire copper plating process is mainly based on the unfolded multi-head copper plating, and the wire drawing and copper plating are separated into two processes. Copper plating, wherein, the copper plating steps include: alkaline cleaning electrolysis - pickling electrolysis - activation treatment - copper plating - water washing - neutralization - water washing - hot water washing - drying - sizing pol...

At present, the existing welding wire copper plating process is mainly based on the unfolded multi-head copper plating, and the wire drawing and copper plating are separated into two processes. Copper plating, wherein, the copper plating steps include: alkaline cleaning electrolysis - pickling electrolysis - activation treatment - copper plating - water washing - neutralization - water washing - hot water washing - drying - sizing polishing - wire take-up, however, in the prior art The speed of copper plating is relatively slow, basically around 250m / min~300m / min, and the process is complicated, the waste of resources is serious, and the energy consumption is high
