Production and application of welding materials
2012-03-26 by seoer6
At present, China has become the world's largest welding materials producer countries, the total output has reached more than 120 million tons on the product structure to the common electrode of the low-grade, high efficiency and high-techWelding Wire China consumables product proportion than smaller. The gap between our welding consumables industry and the industrial countries is no longer yield, but the overall quality and level of scientific research, including the quality of personnel, management level, production equipment and detection technology, product development.
Welding material product structure in China in recent years has also undergone changes, the overall trend is the welding rod production increased year by year to the stable and on a decreasing trend, welding (including gas shielded welding wire and submerged arc welding wire), agglomerated flux production is year by year increase in welding materials of total output growth to slow from the fast and the degree of concentration of generic production of welding materials has increased annually to keep the focus on large enterprises, small businesses are looking to the business of specialty products and specific markets. 2001 kinds of welding materials production, electrode production by 1 million tons of CO2 solid welding wire 130 000 t, 13 000 t in flux cored wire and submerged arc welding material of 120 000 t.
A variety of welding materials production
Electrode manufacturing enterprises in China is about more than 400, which have improved the production conditions, means of detection and quality assurance system of about 250, with a certain production conditions, the lack of detection means 150, the industry-wide production capacity of about 1.5 million tons, far exceeding the market demand. Welding production companies located in all regions except Tibet, part of the machinery, metallurgy, energy, shipbuilding, agriculture and other departments, economic types of state-owned, collective, private, joint venture, sole proprietorship, joint-stock.
Application trend of welding materials
Related to the fabricated metal products with modern welding applications, has great relevance in the petrochemical equipment manufacturing, transport equipment manufacturing, machinery manufacturing, boilers, bridges and construction industry, industry and welding materials industry. The rise and fall of the welding materials industry and is closely related to the development of these industries.
China's shipbuilding system has been made, major shipyard welding efficiency rate in 2005 to more than 80%, welding mechanization, automation rate of about 70%. Shipbuilding industry through the "Eighth Five-Year Plan", "1995" promotion of efficient welding technology has been used in the entire industry, with the development of the process of internationalization of China's shipbuilding industry, the efficiency of the welding material, process dust amount such as a higher requirement.
In short, the application trend of welding material is a high-efficiency, high quality, suitable for use in automatic welding consumables will gradually increase, and other welding consumables, especially low-quality welding consumables usage will be gradually reduced.
The development of welding materials, trends and recommendations
3.1 "15" during the development of welding materials trend
Ordinary low-cost electrode production has been close to the limit, such electrode production will be gradually reduced, special electrode (refer to the low hydrogen, heat-resistant steel, stainless steel, nickel base and surfacing electrode, etc.) the ratio will improve , the electrode output will remain unchanged, but its proportion in the welding material will be close to 80 percent in the current gradually decreased to below 70%.
3.2 Welding materials development proposals
(1) large-scale welding materials enterprises to speed up the adjustment of product structure and product optimization and upgrading.
(2), small enterprises to the development of specialty products, market-specific business direction.
(3) research and development investment, improve the quality of old products, the development of new high-tech products.
(4) Welding Fluxconsumables industry organizations should further play a coordinating role of industry organizations to promote the welding material manufacturers and raw and auxiliary materials production enterprises between exchanges and cooperation, and promote the progress of welding materials industry.
