Application and development of welding materials affect the development of welding technology, steel quality improvement and the improvement of varieties, all kinds of equipment manufacturing industry, the quality of infrastructure and the promotion of key projects, welding materials, higher technical requirements, such as heavy-duty machinery, petrochemical, pipeline containers, nuclear power and hydropower, bridge vehicles, ships aerospace and large construction projects. China's consumption of steel and welding consumables still sustained growth trend. In the environment of industrialization and urbanization development, urging the replacement of welded steel and welding materials, spur the rapid development of welding technology. Welding materials product development strategy to gradually shift from a higher degree of automation and efficient intelligent products gradually replace handmade products, hand welding products gradually to high-strength, high toughness, low hydrogen, environmental protection direction to meet different kinds of steel, different welded structures, different welding techniques under different conditions of service requirements. Development of energy conservation, efficient and high quality new welding material is imperative. Welding is a permanent connection to the material and manufacturing technology into a given functional structure. Almost all of the products, from ship hundreds of tons to less than 1 gram of microelectronic components. Both in manufacturing welding technology applied to varying degrees. Welding has penetrated into all areas of manufacturing, a direct impact on product quality, reliability and longevity and production costs, efficiency and market responsiveness. Welding techniques including welding materials, equipment and technology and other related content, which is the basis of welding material welding technology development.
