Daqiao welding materials group, daisi town, xiqing district, tianjin city, keeps innovating in the manufacturing process. After half a century's development, the group's manufacturing has completely reached the leading level in China. In recent years, the group has continuously improved its independent research and development capability, developed and produced a new welding material -- flux-cored wire on the basis of producing traditional electrode and solid wire, and realized large-scale production.
Flux-cored wire is developing rapidly in recent years a new welding material, can adjust the cored by type and proportion of additive, very convenient to design all kinds of different USES of welding materials, by the flux-cored wire welding with steel belt, after roll up to become a u-shaped cross section, powder filling in the u-shaped slot metal sealed roll, tightly roll this powder in tube type wire inside, then after a series of smoke pull for forming O wire flux-cored wire, widely used in Bridges, vessel, pipeline welding construction and military products.
Under the leadership of cui wei, deputy chief engineer of the group, the reporter came to the production workshop of flux-cored wire. Pick up a flux-cored wire, the reporter did not see what the difference. "This wire is the high-end flux-cored wire of daqiao group's killer mace product. It may not look like anything, but its core technology is in its powder. Powder through our eyes this filling machine uniform, stable, accurate injection into the wire, so as to ensure the quality of the product.
When asked about where is the advantage of flux-cored wire, Cui Wei said: "compared with the traditional electrode and solid wire flux-cored wire has obvious advantages, because the flux-cored wire has mechanical properties and chemical compositions of the welding electrode of adjustable, but also has solid for continuous wire, welding wire with high efficiency and welding quality, in line with the welding production to develop in the direction of high efficiency, high quality, low cost of the trend. Therefore, the proportion of flux-cored wire in welding materials is increasing year by year. The output of flux-cored wire in China has grown from less than 20,000 tons in 2002 to 500,000 tons at present, accounting for 10.5% of the total output of welding materials. It is widely used in shipbuilding industry, steel structure industry and petrochemical industry. And after the formation of beautiful welding, there is a tendency to replace solid wire. At present, the bridge's flux-cored wire products have passed the classification society certification of the United States, Britain, France and middle eight countries, and the annual sales volume has reached 40,000 tons, ranking the first in China, the product development potential is very great. This year, the group will also enrich the variety to gradually meet the market demand.
Daqiao group has seized the rare opportunity to develop flux-cored wire for more than 3 years to realize mass production. At present, flux-cored wire of the group includes flux-cored wire of gas protection, self-protection, stainless steel (purchased and supplied by the product store), flux-cored wire of heat-resistant steel, etc., with more than 100 varieties.
With the development and production of fluxcored wire, daqiao group has been recognized as a national high-tech enterprise and has enjoyed many preferential policies from the state and tianjin, which has added momentum to the future production and development of the enterprise. In the next step, the group will replace its leading products, comprehensively improve the toughness index of welding wire deposited metal, and invest more energy in developing specialized cored wire, such as the cored wire applied in nuclear power field and the surfacing cored wire applicable to the repair welding of abrasive tools, etc.
Bridge group combined with the needs of special industries, targeted research and development of welding materials products, and achieved fruitful results. The low hydrogen and high toughness acid flux-cored wire developed has passed the joint certification of 10 national ship inspection organizations, and the product level has reached the international leading level. The solid welding wire which is suitable for pipe steel welding is developed, which breaks the rule of foreign pipe welding materials. The electrode and flux cored wire of refractory and weathering steel are developed. Moreover, these products have obtained national invention patents and reached the international advanced and domestic leading level. After being put into the market, they have been highly appraised, which has replaced the import and brought great benefits to the enterprise.
Every year, the group invites classification societies of various countries to carry out product certification, the certification of products including electrode, solid wire, flux-cored wire, the product category has reached 35, the invitation of countries also expanded to 10. In recent years, the bridge group fruitful in science and technology innovation activities, has won the municipal, district-level science and technology progress prize 6 items, tianjin science and technology achievements certificate 35, 37 authorized patents, 25 products awarded 10 countries classification society product certification at home and abroad, 10 products through the European product certification, multiple projects for industrialization of national torch plan project industrialization projects, the torch plan of tianjin, tianjin science and technology support plan, tianjin high and new technology achievement transformation projects, national and municipal small and medium-sized enterprise technology innovation project, tianjin energy-saving projects, etc.
A thousand ships compete. Instead of sleeping on "number one," the bridge is targeting the market and "pursuing sustainable development." With advanced technology and advanced concept, the bridge strives to provide customers with satisfactory products and services and continuously contributes to the prosperity and development of the economy.
