Problems solved by technology

However, copper plating on the surface of welding wire inevitably has the following problems: 1. According to the provisions of the national standard GB / T8110-1995, it is allowed to consume 20Kg of copper sulfate when plating one ton of welding wire; deal with
This technology also cannot complete the production of non-copper-plated welding wire in the process of drawing welding wire, but it needs to increase the production process of coated graphite, which increases the investment in equipment and the consumption of chemical materials such as acid and alkali.

Abstract

The invention provides a lubricant which is used in the protection of the production of solid-core welding wires by using non-copper-plating carbon dioxide gas and a production technology of the welding wires. The lubricant is formed by mixing graphite and ferrous oxalate. The production technology of the welding wires comprises: steel wires with the diameter of Phi 5.5mm for welding are firstly drawn to the semi-finished welding wires with the diameter of Phi 1.865mm; the semi-finished welding wires with the diameter of Phi 1.865mm are drawn to the finished welding wires; the production technology is characterized in that: the lubricant which is formed by mixing the graphite and the ferrous oxalate is added in a mould box of the final two or three-channel mould during the drawing process into the finished welding wires; or the mixture of water-soluble dry wire drawing lubricant and triethanolamine stearate is added in the mould box of the former one or two-channel mould before adding the lubricant. When in welding of the non-copper-plating welding wires which are manufactured by the technology, the spatter is less and the metal coating performance is good. The rust-proof period of the welding wires which are packaged by thermoplastic thin films can reach more than three years.

Description

technical field [0001] The invention relates to carbon dioxide gas-shielded solid welding wire, and more specifically belongs to a lubricant for the production of non-copper-coated carbon dioxide gas-shielded solid welding wire and a welding wire production process thereof. Background technique [0002] Carbon dioxide gas shielded solid wire is widely used in shipbuilding, boiler, automobile and machinery manufacturing industries, and the surface is coated with a layer of copper film. Its function: one is to prevent the welding wire from rusting; the other is to use the lubricating effect of the copper film to feed the wire smoothly during automatic welding; the third is to have excellent electrical conductivity of copper, which is beneficial to welding operations. However, copper plating on the surface of welding wire inevitably has the following problems: 1. According to the provisions of the national standard GB / T8110-1995, it is allowed to consume 20Kg of copper sulfate ...
