China is the largest country in the world steel consumption and the consumption of Welding Materials . According to 2006 statistics, China's steel output of 420 million tons, accounting for 34% of the world's steel production, welding material production 3.2 million tons, about 50 percent of the world's welding consumables production. This article describes China's future demand trends of welding consumables, analysis by region and by industry demand conditions outlined welding materials in the future development trend.
First, the welding consumables market demand trends and the current demand conditions by region and by industry
1, the market demand will continue to rise in the 16th CPC National Congress report makes clear, China in the 21st century the first two decades one of the main task of economic construction, basically accomplish industrialization. Now China is in the medium-term development stage of industrialization. The course of the world show that when a country is in the industrialization period, the consumption of steel and welding consumables will continue to grow. For example, the United States and Japan are basically completed the industrialization in the 1970s, the consumption of steel and welding consumables peak, and then to decline steadily. Next 10 years, China's steel and welding consumables consumption will continue to continued growth, but growth rate will moderate slowdown, and focus on attention to the adjustment of product variety and quality improvement. Measured according to the experts, 10 years after China's steel consumption may reach 6 to 700 million tons. Therefore a corresponding demand for welding materials may reach 400 to 4.5 million tons. 2, according to the geographical distribution of demand conditions in China's economic development, regional differences. 3, the demands of the industry by industry demand, the biggest difference between China's steel and welding consumables and developed countries: in recent years, China's construction steel accounts for about 55%, less than 45% of the industrial manufacturing of steel, while the United States, the construction of steel in Europe and Japan accounted for only 22% to 30%, the industrial manufacturing of steel accounted for 60% to 66%. This difference reflects the characteristics of the current stage of development in China, a large number of infrastructure and urbanization.
Two, the main development trend of the welding material
A welding automation progress to promote the adjustment of the welding consumables structure of varieties the mid-1980s, the proportion of developed countries electrode accounted for welding consumables is about 50%. 2004 in Europe, North America (U.S. and Canada), in the consumption of welding consumables, welding rod ratio have been less than 20%, that is, the developed countries of the automation and semi-self of welding, accounted for the entire welding above 80%.
2, iron and steel scientific and technological progress to promote the upgrading and quality of welding consumables varieties to enhance the country is striving from the direction of the steel power to a steel power has been launched in recent years a large number of upgrading and high-performance high-quality steel, especially the production of iron and steel industry level of equipment and technology has made significant progress, for example, will be put into operation more than 10 sets of plate rolling mill, its performance will exceed the existing mill in Japan and the United States to become the world's new generation of modern plate rolling mill for the realization of controlled rolling and cooling ( TMCP) technology, the production of high-volume, high-performance plate, laid the basic equipment.
Wide range of large ordinary welding consumables should be promoted to higher prices for better quality, market-oriented China's current production and consumption of the most common welding materials, including carbon steel electrode junction 422, HJ431 welding flux, ER50-6 copper wire, etc. products, production capacity expansion, oversupply, and the domestic and export prices of our ordinary welding materials, only the equivalent of 50-60% of the similar high-quality welding consumables prices in international market, some of the welding consumables enterprises adopted a "low-cost, low the vicious competition of quality, low price "means, so quite a few users in recent years reflect the quality of some node 422 welding rod and other common welding consumables, not only no progress, but moving backwards. Foreign markets to reflect some of China's export enterprises ordinary welding consumables is low quality parallel imports ", although the price is cheap but the quality is not good, only minor works to the China Welding Consumables image caused by a bad influence.
4, and promote cooperation with the steel mills, to solve the problem of shortage of wire variety of welding consumables development of the major bottlenecks is the variety and quality of gas shielded solid wires and submerged arc welding solid wires can not meet market demand. Including a variety of different intensity levels of high-strength steel wire, heat-resistant steel wire, low temperature steel welding wire, resistant to atmospheric corrosion of steel wire, Stainless Steel Welding Wires.
As for the domestic and foreign manufacturers have introduced the so-called copper wire, it should be known as special coated wire, the coating composition of the manufacturers and surface treatment differences in the performance of wire there are also different. The excellent performance of the coating and surface treatment process, not only from the rust and the role of lubrication, copper welding does not produce soot, but also to enhance the wire arc stability and reduce spatter.
Domestic and foreign manufacturers in the wire coating and surface treatment technology continues to improve. Expect this wire and precise control of the arc-transition digital inverter welding machine compatible, you can achieve high efficiency, high-current low spatter CO2 welding, reaching the equivalent of the flux cored wire welding process, is the future direction of development.
