Gas Protection Welding Wire is widely used for high speed backing welding industry, especially for steel pipelines which produced by X65, X70, steel structures with
450Mpa or 500Mpa tensile strength, and low alloy steel, such as engineering machinery, bridges, high pressure vessels and so on.
1.Clear the oil and rust on the products before welding.
2.The shielding gas flow with about 20~25L/min.
3.Wire extension length with about 15~20cm.
4.The humidity is less than 60%
