Welded pipe welding method and its application in modern industry

Welding is a common method in industrial applications, and by heat or pressure, or both, and with or without filler material. The substance of welding is through the appropriate physical - chemical processes, so that the two separation surfaces of the metal atom to form a metallic bond close to the lattice distance (0.3 ~ 0.5nm) so that the two metal integrally. Welded pipe welding is a welding method, it relates to metallurgy, electrical, physical, chemical, and mechanical.

As we all know, the machinery manufacturing industry is the basic industry of the national economy, which determines a country's industrial production capacity and level of welded pipe welding technology, which is one of the key technologies in the machinery manufacturing industry. Welded pipe welding technology in many industrial sectors have been a different application.
Energy industry: the energy industry, including many areas, such as oil, natural gas, coal, and so on, these industries are required to manufacture a large number of chemical containers, fractionation unit and various tube before welding process occupies a significant proportion of the amount of oil platforms welding is not only large and refining equipment, and technical requirements.
Iron and steel industry: iron and steel industry is the basis for the development of the welded pipe welding technology, welding structural steel in the industrial countries more than half of the production of steel.
In addition, welded steel pipe welding applications in the shipbuilding industry, the automotive industry, the aerospace industry in the country's industrialization era, welding technology has become more sophisticated, great significance to the economic development of the country. In addition, surface mount technology GF used in the electronics industry, one of its core content is microelectronics soldering connections.
