China has the largest consumption of steel and welding materials in the world. According to the relevant statistics in 2006, China's steel output is 420million tons, accounting for 34% of the world's steel output, and the output of welding materials is about 3.2 million tons, about 50% of the world's welding material output. This paper introduces the development trend of welding material demand in China in the future, analyzes the current demand situation according to region and industry, and describes the development trend of welding materials in the future. 1、 The report of the 16th National Congress of the Communist Party of China, which is the trend of the development of the market demand for welding materials and the current demand situation according to the region and industry 1. The report of the 16th National Congress of the Communist Party of China clearly points out that one of the main tasks of economic construction in the first 20 years of the 21st century is to basically realize industrialization. Now China is in the middle stage of industrialization. The process of all countries in the world shows that when a country is in the period of industrialization, the consumption of steel and welding materials will continue to increase. For example, when the United States and Japan basically completed industrialization in the 1970s, the consumption of steel and welding materials reached the peak before it fell steadily. In the next 10 years, the consumption of steel and welding materials will continue to increase, but the growth rate will moderate slow down, while the focus is on the variety adjustment and quality improvement of products. According to the relevant experts' prediction, the steel consumption in China may reach 600-700million tons in 10 years. Therefore, the demand of welding materials may reach 4-4.5 million tons. 2. The demand situation according to the distribution of regions is different in the economic development of our country. Table 1 shows the proportion of steel consumption by Region in recent years. Due to the lack of statistics on this aspect of welding materials, the data shown in Table 1 can also be indirectly considered as the demand status of welding materials by region. 3. According to the demand of the industry, the biggest difference between China's steel and welding materials and developed countries is: in recent years, China's construction steel accounts for about 55%, industrial manufacturing steel is less than 45%, while the current construction steel in the United States, Europe and Japan accounts for 22% - 30%, and that of industrial manufacturing industry accounts for 60% - 66%. This difference also reflects the characteristics of the current development stage in China, and a large number of infrastructure and urbanization construction are carried out. 2、 The main development trend of welding materials 1. The progress of welding automation promotes the adjustment of welding material variety structure in the mid-1980s. The proportion of welding rod in developed countries is about 50%. By 2004, the proportion of welding rods consumed by Europe, North America (USA and Canada) and Japan was less than 20%. See Table 2. That is to say, the automatic and semi-automatic welding in developed countries has accounted for more than 80% of the total welding workload. 2. The progress of steel science and technology promotes the renewal and upgrading of welding materials and the improvement of quality. China is striving to develop from a large steel country to a powerful steel country. In recent years, a large number of upgraded and high-quality steel have been launched, especially in the technical level of production equipment in the steel industry, for example, more than ten sets of medium and thick plate rolling mills will be put into operation successively, The performance of the mill will exceed the existing mills in Japan and the United States, and become a new generation of modern medium and heavy plate rolling mills in the world. It lays the equipment foundation for realizing the TMCP process and producing large batch and high performance medium and heavy plates. 3. For the common welding materials with large quantity and wide range, we should promote the market orientation of high quality and good price, including the most common welding materials produced and consumed in China at present, including carbon steel electrodes such as jie422, HJ431 flux, ER50-6 copper plated welding wire, etc. due to the expansion of production capacity and oversupply supply, the domestic and external sales prices of common welding materials in China are made, All of them are only 50-60% of the price of the same kind of high-quality welding materials in the international market. Some welding material enterprises have adopted the vicious competition means of "low cost, low quality and low price". In recent years, many domestic users have reflected the quality of some ordinary welding materials such as knot 422 welding rods, which has not improved but stepped back. The foreign market reflects that some enterprises export ordinary welding materials as "low quality water goods". Although the price is cheap but the quality is not good, they can only be used in secondary projects, which has caused bad influence on the image of welding materials in China.
