At present, China has become the world's largest producer of welding materials with a total output of more than 1.2 million tons. The product structure is still dominated by low-grade ordinary electrodes, and the ratio of high-efficiency and high-tech welding products is relatively high. small. The gap between China's welding industry and industrialized countries is not in terms of output, but in terms of overall quality and scientific research, including personnel quality, management level, production equipment, testing technology, and product development.
In recent years, the structure of China's welding material products has also changed. The overall trend is that the output of welding rods will increase year by year to a stable and decreasing trend. The output of welding wire (including gas-shielded welding wire and submerged arc welding wire) and sintered flux is increasing year by year. With the increase, the total output of welding materials has also increased from fast to slow. The concentration of general welding materials production has increased year by year, and has continued to be concentrated in large-scale enterprises. Small-scale enterprises are seeking specialty products and operating in specific markets. In 2001, the output of various welding materials in China was 1 million tons of welding rod, 130,000 tons of CO2 solid wire, 13,000 tons of flux-cored wire, and 120,000 tons of submerged arc welding material.
1Production of various welding materials At present, there are about 400 welding electrode manufacturing enterprises in China, of which about 250 have perfect production conditions, testing methods, and reasonable quality assurance systems. There are nearly 150 companies with certain production conditions and lack of detection methods. The industry-wide production capacity is about 1.5 million tons, far exceeding the market demand. Welding electrode manufacturers are located in various regions except Tibet. They are affiliated to various departments such as machinery, metallurgy, energy, shipbuilding, and agriculture. The types of economy are state-owned, collective, private, joint venture, sole proprietorship, and joint-stock companies.
2 Application Trends of Welding Materials The related metal products industries are all related to modern welding applications. They have a great correlation with the welding material industry in petrochemical equipment manufacturing, transportation tool manufacturing, machinery manufacturing, boiler, bridge and construction industries. Sex. The rise and fall of the welding materials industry is closely related to the development of these industries.
China's shipbuilding system has been proposed that by 2005 the welding efficiency of major shipyards should reach over 80%, and the mechanization and automation of welding should reach 70%. The shipbuilding industry has been promoted through the "85" and "Ninth Five Year" decade of high efficiency welding technology and has been used in the entire industry. With the development of the internationalization of China's shipbuilding industry, the efficiency, craftsmanship, and development of welding materials have been increasing. In terms of volume and other aspects, higher requirements have been put forward.
In short, the trend in the application of welding materials is that high-efficiency, high-quality welding consumables suitable for automatic welding will gradually increase, while the use of other welding consumables, especially low-quality consumables, will gradually decrease.
3 Development Trends and Recommendations for Welding Materials 3.1 Development Trend of Welding Materials during the 10th Five-Year Plan Period As the output of ordinary low-priced electrodes has approached the limit, the output of such electrodes will gradually decrease in the future, and special welding rods (referring to low hydrogen The proportion of heat-resistant steel, heat-resistant steel, stainless steel, nickel-base and surfacing electrodes, etc. will increase, and the total output of welding rods will remain unchanged, but the proportion of the total welding material will gradually decrease from the current 80% to 70%. the following.
3.2 Development proposals for welding materials (1) Large-scale welding materials companies accelerate product structure adjustment and product optimization and upgrading.
(2) Small and medium-sized enterprises develop into characteristic products and specific market operations.
(3) Investment in research and development to improve the quality of old products and develop new high-tech products.
(4) The welding consumable industry organization should further develop the coordination role of the industry organization, promote the exchange and cooperation between the welding material production enterprises and the original and auxiliary material production enterprises, and promote the progress of the welding material industry.
