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.
