It is understood that the welding equipment known as "industrial sewing machine" is an important process equipment in modern industry. It is widely used in the efficient connection of metals and alloys, which directly affects the quality, reliability and service life of products, production cost, efficiency and market competitiveness. Driven by China's sustained and rapid economic growth and the acceleration of industrialization, urbanization and modernization, a number of industries related to the national economy and the people's livelihood, such as railways, shipbuilding, oil pipelines, construction and automobiles, have strong demand for steel, creating huge business opportunities for the welding equipment market.

According to experts from China Welding Association, according to the calculation of 25 welding machines per 10000 tons of steel, China's steel output reached 490 million tons in 2007, requiring a total of about 1.25 million electric welding machines. However, due to the limitation of domestic production technology and process, medium and high-grade automatic and semi-automatic arc welding machines, resistance welding machines, special welding machines and special complete sets of equipment, which account for about half of the total domestic market every year and are worth US $1 billion, still rely on import.
