Abstract

The present invention relates to welding material, in particular to a welding wire used for X 70 pipeline steel and low-alloy steel, pertaining to the field of the welding material. The non-copper-plated submerged arc welding wire provided by the present invention includes the following elements according to the weight percentage: 0.06 to 0.10 percent of carbon, equal to or less than 0.07 percent of Si, 1.50 to 1.90 percent of Mn, equal to or less than 0.02 percent of phosphor, equal to or less than 0.015 percent of sulfur and equal to or less than 0.40 percent of nickel. The manufacturing process of the welding wire includes the following procedures: a lubricant is added when the welding wire is drawn; the residual lubricant on the surface of the welding wire is eliminated by electrolytic alkali cleaning, washing and electrolytic acid cleaning after the welding wire is drawn to the diameter required; then an anti-rust oil is added and the welding wire is polished by soft metal material. The welding material of the present invention has the advantages of good welding quality, excellent electric conductivity, wire feeding property and rust resistance, which can replace the original copper-plated submerged arc welding wire.

Description

A kind of copper-free submerged arc welding wire and its preparation method technical field The invention relates to a welding material and a preparation method thereof, in particular to a non-copper-plated submerged arc welding wire and a preparation method thereof. It belongs to the field of welding materials. Background technique As my country's energy demand continues to increase, it will directly drive the development of my country's oil and gas pipelines. Considering factors such as economy, safety and transportation efficiency. PetroChina and Sinopec have increased their demand for oil and gas pipelines. This also drives the demand for pipeline steel welding materials. At present, the traditional copper-plated submerged arc welding wire is mainly used in major steel pipe factories. The traditional copper-plated submerged arc welding wire has a series of advantages: high deposition efficiency, good electrical conductivity, such as dense copper plating, it has goo...
