Welding as a general **** technology, in the manufacturing industry by a considerable number of enterprises as a key process, welding directly determines the quality of their products. These enterprises constitute the main body of welding technology application.
According to the method of division of China's industrial categories, this part of the enterprise is widely distributed in the boiler, pressure vessels, power generation equipment, nuclear facilities, petrochemicals, pipelines, metallurgy, mining, railroads, automobiles, shipbuilding, port facilities, aerospace, construction, agricultural machinery, water conservancy facilities, construction machinery, machine building, medical equipment, precision instruments and electronics and other industries. These enterprises in China's industrial economic construction in the deep impact, wide-ranging, pivotal impact and role. According to incomplete statistics, these welding as the main processing technology (or welding has a key impact on the quality of its products) the number of enterprises amounted to more than 7000.
China's existing welding equipment manufacturers thousands. Among them, the number of welding equipment production enterprises is about 900, the number of welding material production enterprises in more than 500. In addition, there are hundreds of enterprises engaged in welding auxiliary equipment, supporting apparatus, cutting equipment and related safety supplies manufacturing. These enterprises constitute the main body of China's welding equipment supply industry.
According to the National Bureau of Statistics issued the "2003 National Economic and Social Development Statistics Bulletin", China's steel production in 2003 was 220 million tons, an increase of 21% over the previous year. According to the rate of 40% of China's welding steel consumption, the amount of welded structures close to 90 million tons of steel.
The Prospect Industry Research Institute believes that, while in industrially developed countries, the amount of steel used in welding basically reached 60% -70% of its total steel. According to China's national economic development in 2020, the overall goal of the requirements and the development trend of China's welding industry predicts that China may reach the level of 60% in the next 5 to 10 years time. By then, China's steel production will be between 250 and 300 million tons. This means that the amount of welding will double, which creates a sizable demand for welding productivity and labor. Taking into account the actual space of China's welding productivity growth, productivity and labor force linkage between factors such as the future demand for China's welding labor force may be more than a million orders of magnitude. Therefore, the welding industry will continue to grow in the next 5 to 10 years.
On the eve of entering the 21st century, the American Welding Society (AWS) has organized authoritative experts to discuss and formulate the United States in the next 20 years, the development of the welding industry strategy. Its analysis of the welding future made the following predictions: in 2020, welding will remain the preferred method of connecting metals and other engineering materials. U.S. industry will rely on its leadership in joining technology, product design, manufacturing capabilities and global competitiveness to become the world's leading provider of these cost-effective, high-performance products.
It is not difficult to see: welding in the future of the industrial economy not only has a wide range of applications, but also on product quality, manufacturing capacity of enterprises and their competitiveness to have a greater impact.
After joining the WTO, as the world's largest developing countries and the most economically dynamic countries, the development of China's welding industry is full of opportunities and challenges. How to effectively grasp the opportunity to meet the challenges to ensure sustainable and healthy development in the future, is an important issue facing China's welding industry.
