According to China's long-distance pipeline construction of the development process, sum up the whole fiber, hybrid, complex three kinds of manual welding techniques and to the activity under the gas, flux cored wire from under the protection of two kinds of semi-automatic and automatic welding technology activity to flux-cored arc Welding Wire and automatic welding technology to the next process characteristics and long-distance pipeline construction in China in the application state that the automatic and fully automatic active gas shielded flux-cored welding to weld will be our next long-distance pipeline under the direction of the welding technology.

With oil and gas and petrochemical industries to natural gas projects as a symbol of China's long-distance pipeline construction peak has arrived. More to the long-distance oil and gas pipelines of large diameter, high-pressure transmission direction. Under the long-distance pipeline welding technology since the 1960s since the introduction of our country, after decades of development, now under the hand of a mature technology to welding, are popular semi-automatic gas shielded welding technology, welding technology and automatic gas under the combination of the welding technology as a long-distance pipeline welding technology trends, will be in the national long-distance pipeline construction to promote.
