Gas-shielded welding method with its unique advantages in the industrial countries has been manufacturing a wide range of applications. Development to date, gas-shielded solid Aluminium Welding Wire for the United States account for about 31% of the total welding consumables, Japan 41%, 53% in Western Europe. Gas shielded arc welding process development and manufacture of metal structures are inseparable. Currently in the United States, Japan, Europe and other developed countries and regions using the ratio of welded structure increasing consumption of welding gas welding metal weight of about the total weight of all the welding material of 50% to 75%. Gas welding technology, which greatly improved the metal structure manufacturing technology.
China's gas research and development of Welding Wires began in the 1950s, but always remain at the research stage. Over the past 10 years, solid wires for gas shielded the development of faster, now the country's gas production of solid welding wire more than 150 companies, from Germany, Sweden, Canada, Japan and other countries and Taiwan imported 50 sets of production equipment, or self-developed equipment made more than 100 articles, the production capacity of 200,000 tons. In 2002, total production of welding consumables is about 1.5 million tons. Production of solid wire about 25 million tons, accounting for about 17% of the total welding consumables, but the comparison with foreign countries, there is a big gap.
By the Naval University of Engineering Professor, Gui Chi Bin led the invention of new drugs developed by die bonding material has passed the experts. The product uses advanced flux-cored welding materials, improve
The quality of welded joints and Welding Wire China efficiency and improve the level of China's shipbuilding welding, reached the international advanced level.
It is learned from the 1950s China started to develop flux-cored wire, but until now, foreign FCW continues to occupy half of China's market share. Professor Gui Bin developed a new type of red-cored Flux Cored Welding Wires
Materials, to solve the ship demanding technical requirements of welded joints can achieve high strength, high toughness and crack resistance wire, anti-holes and other excellent properties, which can be important in countries such as electrical engineering
Stations, bridges, oil pipelines and other long-distance transmission play an important role.
