Welding equipment is an important process in modern industry. It is used in the efficient connection of metals and alloys, which directly affects the quality, reliability and life of products, as well as production costs, efficiency and market competitiveness. It is a metal processing technology constructed together with metal processing such as metal cutting, pressure processing, casting, and heat treatment, and is an important processing technology in the modern machine manufacturing industry.

Driven by the continuous rapid growth of China's economy and the accelerated process of industrialization, urbanization and modernization, welding equipment known as "industrial sewing machines" is widely used in petrochemical, electric power, aerospace, marine engineering, nuclear power engineering, microelectronics technology, bridges , ships, submarines, and various metal structures and other industrial sectors, according to incomplete statistics, the annual output of steel and a large number of non-ferrous alloys in the world are all put into use through welding, creating huge business opportunities for the welding equipment market.

It is no exaggeration to say that without the development of modern welding technology, there would be no modern industry and science and technology today. The development level of welding technology is one of the important indicators to measure the advanced level of a country's science and technology.
