英文摘要：

It is described the characters, utilities and development orientation of the inverter welding power source, then analyzed its problems and put forward some methods to deal with them. With the development of economy and manufacturing, the inverter welding power must take place of the traditional arc welding power source generally. At present, there are some disadvantages such as unreasonable structure of product, inferior quality, insufficient of originality innovation and so on in the inverter welding power. So with the gradual maturation of electric and electron technology and digitized control technology, the development orientation of inverter welding power source transfer to be greener,higher efficient and more digitized.
