  Constructure steel of building with light weight and short construction period, adaptable,a rich profile, easy maintenance, etc., and their use is widespread. From the age of 80 since the 20th century, Chinese steel building has undergone an unprecedented development, in 2005, China has become the world's largest steel production and steel, in steel consumption has exceeded 300,000,000 tons, of which the steel structure Production of up to 140,000,000 tons, including energy, transportation and infrastructure construction such as the steel industry has become a pillar of national economic construction.

Since 1949, China's steel structure has gone through difficult times, the low tide period, the development period, the four stages of maturity. At present, China's steel structure has entered a mature stage. Entered the mature stage is marked by the "bird's nest," the successful completion of welding steel structure, which a century for the smooth completion of the project, give a strong impetus to China's construction technology and the rapid development of iron and steel industry, signs of China's iron and steel industry and construction technology Into the world's advanced industry. At the same time a large number of innovative design, exquisite materials of the steel works came into being. China's steel industry so that there have been thriving, prosperous development of the good situation

In this paper, "nest" welded steel works in welding technology as the main clues to work on the development trend of steel, for reference

First, China's construction works welded steel structure of a typical project

So far, China has built more than 60 blocks of high-level welded steel construction; long-span space steel structure in a variety of sports centers, exhibition centers, theaters, terminal, hangars and a number of factories in industrial applications; steel bridge in the ascendant ; Domestic steel in China in recent years through in-depth research and development, also has entered a new stage of development
